Well, technically it was Madagascar...but I've seen that before, and I only watch the bits with the singing/dancing Lemurs :)
I've seen three this year though:
Indiana Jones and the Kingdom of the Crystal Skull. One word ruins it: aliens. By inserting aliens into the plotline, they killed it. I did like the bit on the bike though.
Iron Man. This was worth the watch. Absolutely brilliant. I just didn't find anything wrong with it.
Iron Man 2. Again, good. I disliked how they had a different actor for the same character between two films, but it was the guy out of The Italian Job and Ocean's Eleven/Twelve/Thirteen, and he's awesome so I didn't care.
I saw "Four Lions" just before 2011. That was hilarious, and I would recommend it. The fact that the ending was emotional was good too.
And a film I saw in September, "Three Kings" with George Clooney and Mark Wahlberg. Definitely worth a watch. Its funny, tragic and slightly political (although out of date now) at the same time. The ending was almost moving, but the whole film wasn't too serious on the surface.
