The Groove Tube and especially Kentucky Fried Movie.
Yeah, me too. Nature Unleashed: Avalanche and Vertical Limit as well.
I own the first two Step Up movies because I love them to death. Especially the final dance sequences in each.
And, along the lines of Unauthorized Cinnamon’s pick, I’ll add Holiday in Handcuffs. Girl gets dumped on Christmas Eve, right before her boyfriend is to meet her family. She solves this problem by kidnapping a handsome stranger and making him go to her family’s Christmas celebration, insisting he’s a “kidder” when he complains about being someone else. Stockholme syndrome sets in of course. Awww.
I forgot about Dante’s Peak! I really, really enjoyed that movie. One of the local theaters had a discount double-feature of that and whichever Mummy movie was out around that time. I believe I paid at least three separate times for that double feature.
Big Trouble in Little China is an action-comedy classic. Period.
Boogie Nights was, IMO, the best movie in its Oscar class.
Hey, Buckaroo Banzai is awesome!
I love Big Trouble in Little China, will stop and watch Demolition Man any chance I get, and still geek out over The Last Starfighter and Battle Beyond the Stars.
Abbott & Costello Meet Frankenstein
Any Bela Lugosi Poverty Row and Monogram or Ed Wood films
I’m sure I’ll think of some more.
Dune. I’m pretty familiar with the source material and I’m aware of all the movie’s flaws. I don’t care. My love for this movie is vast.
Vast.
Scotty doesn’t know is a great song.
Yeah! I’ve never seen the movie, but I heard the song about five years ago and fell in love with it.
It ended 15 minutes too late. The final scene should have been that long, long close-in on Dirk’s face, fade to credits.
Not hating on you guys, glad you like it. But maybe six years ago a friend of mine was just raving about how great this film was, and how I’d love it. He’d bought the DVD and forced me to borrow it.
I had it on, just in the background. I was playing WoW at the time (still addicted back then.)
Even despite multitasking and hardcore WoW gaming with Grandma’s Boy in the background, I still turned it off after 30 minutes or so. It offended my aesthetic sensibilities that badly. God, I hated that movie. 
But if you enjoy it, hey! Glad someone likes it! 
Actually The Fifth Element was perfectly, perfectly evocative of Jean Giraud/Moebius’ work from Heavy Metal magazine. Particularly The Incal. Giraud worked on the film and later sued Luc Besson for ripping him off. He lost, but really visually it is dead on. So it is very much in the theme of something, that something being Heavy Metal’s cock-eyed take on over the top, colorful, bizarre action sf.
Love the film, by the why. As with many others I can’t not watch it or Big Trouble in Little China when they pop up on the screen.
I’ll watch Godfrey Cambridge in Watermelon Man any time it’s on. (But it never is!)
Biggles.
“If you can fly a Sopwith Camel, you can fly anything!”
/bad redneck accent
“Put the bunny down…”
No, I know. It’s thoroughly and indefensibly bad. It’s not “Everyone says this is bad, but I think it’s actually kind of good!” It’s “Everyone says this is bad, because they have functioning brains.” Even though I enjoy it, I would never in a million years recommend that someone else watch it. That was extremely uncool on your friend’s part. Even when I showed it to my husband, I was like, “Hey, look! This is that bizarre piece of crap I couldn’t stop watching the other day!” But yeah, someone should like it, right? I mean, it’s got Linda Cardellini, for pete’s sake. I’d hate for her to have gone to all that trouble for nothing.
But as for terrible movies I would recommend…
If you like these, and especially if you also like movies in the cheerleading flavor of this genre, like Bring it On, then allow me to suggest: Drumline. It actually has a pretty good rating on RT, but trust me, it’s bad: trite, predictable, and formulaic. But it’s a lot of fun, and if you’ve ever been in a marching band, you will adore it.
Yep. I call that a good movie, without qualification or irony. I submit that if you think you’re enjoying it despite its badness, you’re not quite getting it.
I also call The 13th Warrior a good movie, though not perfect. Some aspects of production and post-production hurt it; there’s a lot of unreleased footage, and it could stand being recut for an extended edition.
I still occasionally watch parts of “Where Eagles Dare”, even though the plot is confused and ludicrously improbable*, because I like some of the actors (in particular the hot babes).
*“Broadsword to Danny Boy! Broadsword to Danny Boy! Is this the stupidest mission ever, or what?”
It’s only bad because of the ginormous plot holes! The editing, the dialogue, the actors (with exception to the President, wrestlers aren’t articulate enough for the job of President of the Federation), the characters, the timing, lighting, everything was so much fun and what fun sci-fi should be 
Heck, the direction was so good that Luke Perry didn’t even suck.
Aziz! Light!
I’ll take your Dante’s Peak and raise you a Volcano. Easily two to three times better, IMO. Downtown LA? La Brea Tar Pits? Tommy Lee Jones? Anne Heche? Classic.
Also, I’ll confess to the fact that my husband and I both get sucked in irresistibly to The Core. No matter how bad the science, the cast is phenomenal and it’s thoroughly entertaining.
And… it’s now stuck in my head again. I knew I shouldn’t have brought up Eurotrip.
