My nomination is for “Army of Darkness.”
I was on this one submarine deployment years ago, and this movie seemed to be playing just about continuously in the crew’s mess.

They are awesome bad in their own way. I love those movies. Burt Gummer for the win!
So many great dumb movies … and so little time! 
I was going to mention the awesome Flesh Gordon, but somebody beat me to it. Damn!
I’ll nominate Pee-Wee’s Big Adventure instead. The first great collaboration between Tim Burton and Danny Elfman, if I’m not mistaken.
Are movies like Plan Nine from Outer Space, Billy the Kid vs Dracula, and They Saved Hitler’s Brain too stupid to make the cut here? :dubious:
Dr Black and Mr Hyde should be on the list too, if just for Elvira’s interview with Arsenio Hall as Tyrone Washington on Movie Macabre (damned if I can find it on YouTube, though ).
Top Gun was AWESOME!!! I still put on the Kenny Loggins video, crank up the sound, and imagine I’m flying a Tomcat over the Persian Gulf. 
Another entry: The Green Berets with John Wayne. The war in Vietnam becomes good, clean American fun! And Sulu is in it, too, as one of the Good Guys! YAY! 
I’ll argue that they’re not too stupid – they’re just not awesome enough.
I love Plan 9, Robot Monster, and the like. But they’re low-budget and cheap. 10,000 B.C. is Big Budget Awesome. And stupid, to boot.
Beavis and Butt-Head Do America?
Probably not awesome enough either…
Sharknado 2 and it’s not even close. Do any of these other movies have a guy flying through the air on a tornado killing sharks with a chainsaw? No, they don’t.
Shoot 'Em Up does it with style.
Killer Klowns from Outerspace is a contender, but all the human parts aren’t awesome or stupid enough.
Tremors isn’t stupid. The monsters couldn’t move through the ground like that, but everything else is perfectly logical. Disqualified.
Has anyone mentioned The Secret of My Succe$s yet? Because that is an AWESOME-ly stupid (but at the same time, AWESOME) movie.
Second place goes to Stir Crazy.
**Zombieland. **
Did I miss someone already posting that?
Seriously awesome and seriously stupid.
Jason Statham’s The Transporter and Transporter 2 had many highly unlikely stunts but the action was pretty badass. Like the time he had a bomb on the bottom of his car and he flicked it off by doing a corkscrew jump and having the hook of a crane hit it, in mid-air.
Pee Wee’s Big Adventure was definitely stupid, but awesome.
I haven’t seen My Name is Bruce, but I went to a showing of The Evil Dead a couple weeks ago with Bruce Campbell doing a Q&A afterwards. There were many, many fanboys in the audience. Bruce seemed cool with it.
I hadn’t seen The Evil Dead before, either. Interesting movie; just bad enough to be funny, just good enough to be really creepy.
No love for Sharknado? Dumbest premise in movie history but it’s fun and campy.
Lots of good ones so far.
Kick Ass is an awesome good stupid movie. (I didn’t watch the sequel as I didn’t want to sully the original with anything)
The Goonies is a great bad movie.
Should we include the Indy Jones films. They are really stupid if you think about it.
Another vote here for “Shoot 'Em Up,” which was just staggeringly wonderful and stupid. It was the most deliberately stupid movie I’ve ever seen and I loved it.
Some of the movies names so far aren’t stupid at all, though. “Bill And Ted’s Excellent Adventure” is absolutely not a stupid movie. BILL AND TED are stupid, but that’s kind of the point. The movie’s premise is silly as all hell, but it proceeds logically from that premise and throws in some implications of time travel that most time travel movies totally ignore. It’s one of the more clever and logical time travel movies ever made, actually.
This might be an unpopular choice, but the two JJ Abrams “Star Trek” movies are absolutely, drop-dead stupid, and yet both are incredibly awesome. “Into Darkness” is easily as illogically stupid as “Pacific Rim” but I enjoyed every minute of it. Neither of the new Star Trek movies hold up logically at all once you think about it, and yet the films are just an absolute load of fun. Even now, knowing they make no sense at all, I’d enjoy watching them again.
10,000 BC is tvtropes’s “Somewhere a Paleontologist is Crying” turned into a movie.
Galloping mammoths. In ancient Egypt. With north american smilodons. Did you just walk from Europe to Egypt?
I honestly could not enjoy the movie.
Nicholas Cage does have one of the best lines ever:
Star Crash
It wasn’t the blatant anachronisms and displacements that I found truly annoying. It’s that, even if you allow all that stupidity for the sake of the movie – assume it took place in some alternative universe, or a Long Time Ago in a Galaxy Far, Far AWay, if that helps – it’s that the movie is still absurd even on those terms, and the characters fatally dumb.
Our hero falls into a Tiger Pit set with punji sticks into which a 20-foot Smilodon has fallen.
What?
1.) Didn’t the Smilodon leave a HUGE hole in the trap covering?
2.) This is a particularly badly=made trap, since neither Our Hero nor the giant Smilodon (!) gets impaled on a punji stick. A tiny goat did, though, so I guess one out of three ain’t bad.
3.) Our hero, who has an absurd altruistic and optimistic streak in him (or else is the ancestor of Jim Carrey’s character in Dumb and Dumber) decides to free the giant smilodon, which has been trapped in this pit God knows how long, and probably not in a good mood. And probably hungry. In a realistic movie, we’d have next seen an example of Darwin’s principles in action
But, no, the Smilodon has the same goofy sense of altruism, and lets Our Hero go.
But that’s still not the dumbest part. It’s one thing for Our Hero to gamble with his own life, but he’s on a quest to save people of his tribe. It’s kinda stupid to let a giant, hungry man-killing beast loose under those circumstances. Especially when you’ve left a pretty obvious sign- and scent-trail back from the edge of the pit to where your companion is lying wounded. Even if brother Smilodon is insanely grateful to Hero for letting him out of the trap, he has no reason to feel grateful to Hero’s companion. If Smilodons could write (and our Hero could read), I’d expect him to get back to the makeshift camp and find a note saying “THanks for the snack! I owe you one! --Smiley”
