I wish they’d make a sequel to Black Snake Moan. 
And Oliver Reed and Teri Garr and Karl Malden. It was awful
The worst part was that those are some talented people, and David S, Ward, who wrote the original, wrote this one too. It had no period “feel”, no menace, and yopu didn’t care about the characters. Awful all the way around.
Maybe the reason for some of these being as bad as they are is the Son of Kong effect – the studio gives the new production deficient time and resources, hoping to coast on the name alone. It’s not Merian C. Cooper and Ernest Schoedsack’s fault that Son of Kong ended up being as bad as it was.
Son Of The Mask followed The Mask by 11 years, so it qualifies. I’m no fan of Jim Carrey, but he was perfect for the original. The sequel starred Jamie Kennedy, who is only a suitable replacement if you are Jennifer Love Hewitt. I haven’t seen the sequel - but since it was nominated for 8 Razzie Awards, winning one (for Worst Sequel), and got an appalling 5% on Rotten Tomatoes, it’s safe to say it wasn’t as good as the original (which scored a strong 77% on Rotten Tomatoes).
“Temple Of Doom” was pretty awful as well. I watched it on DVD a little while ago for the first time since seeing it in the theater and wow is it lousy.
The Bush Administration made a sequel to ‘9 to 5’ called ‘Are You Guys Hiring?’. 
Shame they didn’t use theoriginal sequel so to speak - I had a copy of this as a child … never read the original tho’.
No, no, I’m pretty sure it was. There were no sequels to Highlander. Ever.
Escape from L.A.
May not count because that was a remake disguised as a sequel. 
I loved Gregory’s Girl but I hear Gregory’s Two Girls is shite. They’re about twenty years apart.
War Games and War Games 2: The Dead Code
I have the DVD of the second one, but I haven’t watched it yet. I’m pretty sure it won’t be great, but I kind of liked the Lost Boys sequel, so what do I know…
I’m surprised nobody’s mentioned The Hustler and The Color of Money, featuring Paul Newman getting an Oscar in the 80’s that was kind of meant for the first movie. It wasn’t terrible and awful and horrible, but it wasn’t great either, and it sure wasn’t as good as the first movie, which is a Great Movie.
Slapshot is the greatest sports movie ever made. Slapshot 2:Breaking the Ice, is an utter atrocity not even worth a used puck bag. I’m shocked that Hanson Brothers even agreed to be a part of it, and anyone that was should go to the box by themselves, you know, and feel shame.
Yikes, I just learned on IMDB that there is a third Slapshot with even worse ratings than the second. I wouldn’t even touch that with Zdeno Chara’s stick.
That’s a case where there is no possible way to win. I thought The Color of Money was a very enjoyable film. Young hotshot now an old man trying to mentor a new young hotshot. But unless it was a better film than it’s indisputably great predecessor, it was going to be considered a failure. The thing is, it was made for an audience that wasn’t alive when The Hustler was in theaters. That audience was there to see Tom Cruise. But to imply that Newman didn’t deserve the Oscar he got for this film is a bit unfair. It was an excellent performance on it’s own.
The other movies didn’t have an indestructible fridge.
Or an alien spaceship.
What are you talking about?
There are only 3 Indy movies.
Or a Monkey Army.
I liked Tremors.
Tremors II: Aftershocks, Tremors 3: Back to Perfection, Tremors 4: The Legend Begins, Tremors V: The Thunder from Down Under? Not so much.
This is a good one. The first one is in my opinion one of the 10 best movies ever made. The second one while not as good as the first is way up there. The third definitely did not live up to expectations. Have any of the others mentioned fallen so far.
Highlander was a good movie. But not Godfather good. On the other hand the rumored sequel was really really awful in a way that Godfather III was not. Which series fell father?
Well, the Godfather movies were all about the fall of the Dons…
