1) Thor TDW: personally I preferred it to Thor, I thought it kept the elements that made the first movie good, Hiddleston was terrific as Loki, and there was a nice balance of humour (although less Kat Dennings would have been good) and action - and the dark elves were appropriately creepy. I quite like that while movie Thor is powerful, he isn't all powerful, especially without Mjolnir, which makes it possible to believe he might not win in the end. Good cliffhanger ending too.
I gave Thor TDW a solid 8/10
2) TASM 2: I didn't like TASM all that much, and while TASM 2 wasn't great as a film, it had some really good moments, and Andrew Garfield was much better as PP/SM. As a sequel it wasn't great, but okay (good ending though and Gwen's death was well handled) and that I can live with.
I give TASM 2 a 6.5/10, not bad at all.
IMO the rest of them were absolute crap, and I would avoid seeing them again as they diminish the original (the most unforgivable being Iron Man 2, which isn' t the worst by a long shot, but was a such a lame follow up to such an amazing first film - a bit like Kick Ass 2).
Ghost Rider: spirit of vengeance was so terrible, that it was actually fun to watch, especially Nic Cage's crazy moments.
GI Joe (the first) was a guilty pleasure, not a good movie, but really fun to watch - the second movie was just awful.
Transformers (the first) was a fun, solid sci-fi actioner.... it was as if Michael Bay made the sequel while on copioius amounts of crack, because was everything good about the first film was amped up and played at double speed - until we had no idea what was going on.
mind you it's a good laugh if you watch the honest trailer
