Let me get in on the action:
Pirates 4: Isn't getting me as excited as the previous 3, and I loved all 3. My favorite was the 2nd one. There is a big lack of Barbossa in the trailer and too much of the new characters.
Thor: Aside from an Issue in the X-Men I know squat about this guy, and the promotion screens made me think it would be some mythological crap, and then their was SEGA produced worst license game of all time. But the trailer was awesome, it might work.
Captain America: Same history as with Thor, but the game actually looks better than the movie, the only thing I liked in the trailer was the idea that the actor lost all that weight and bulked up again (or something to that affect).
Green Lantern: Same history as with the other 2, though I did see Justice League Unlimited and it had John Stewart as the Lantern. Didn't really like Lantern in the animated series, but this here feels more of a cartoon than the animated series.
This movie is going to suck big time, I saw an interview with Ryan Rennolds where he was talking about fixing the script, the writers messed up important quotes of the character that he fixed. If dum actors know the script is messed up, imagine how the badly messed up the script would be and this is the guy who starred in Blade Trinity and Wolverine: Origins.
Not a summer I'm looking forward to based on the trailers.
