Jaws the Revenge(Worthless crap) Anaconda 3(JUST WORTHLESS CRAP) The Sandlot 2(bad acting,attempt of a remake,BAD) Friday The 13th A new Beggining(Jason isnt even in this one) Batman & Robin(WAY TOO CHEESY) Terminator Salvation(No Arnold No Terminator)
Django 2 Highlander 2 (actually all sequels were pretty bad, but 2 was the worst. I have never watched a worse film than this piece of crap) Spiderman 3 (well, effects and stuff might be good, but the story was just stupid in my opinion)
About the good sequels discussion: Man with no Name series (The 3rd one was the best, definatelly) The Dark Knight
Almost all of the sequels you guys have listed so far are terrible, but probably shouldn't be on this list. To me, when discussing bad movie sequels, you have to look at the broadness between how bad the sequel is and how good the original was. For example, Caddyshack is one of my favorite comedies ever, and Caddyshack II was an absolute abortion of a film. That's a good pick for worst movie sequel. Someone also listed The Howling sequels. First one was great (in my opinion) while all the rest were awful, so that's another great choice. On the other hand, while Troll 2 stunk on ice, so did the original, so you can't really call it a bad sequel. As a matter of fact, it might be one of the few films that you can say surpassed the original, because at least Troll 2 is good for a laugh! Something like Baby Geniuses 2 is another good example.
But just to add a few, I'll include: The Ring 2 Jaws 3 & 4 (2 is watchable) Alien: Resurrection All The Sequels To The Omen (though the second has it's moments) All Sequels To The Crow Son Of The Mask
1. Superbabies:Baby Geniuses 2 2. Home Alone 4 3. NeverEnding Story 3 4. Son of the Mask 5. Secret of NIMH 2:Timmy to the Rescue 6. Jaws:The Revenge 7. Troll 2 8. Highlander II 9. Superman IV:Quest for Peace

Worst Sequels eh? I'm not going to count the low-budge straight-to-video junk that gets thrown together with no effort. What I consider to be truly bad are sequels made by competent studios and/or filmmakers with reasonable budgets. With that being said...
- Jaws 3 and 4 - Transformers: Revenge of the Fallen - Batman and Robin - X-Men Origins: Wolverine - Son of the Mask - Dumb and Dumberer - Speed 2 - Troll 2
I'm sure there are more, but I can't think of any others at the moment.
