Best summer blockbuster of 2010: Iron Man 2; Toy Story 3, Shrek 4, Despicable Me?

I loved toy story 3 the most. I guess it's because I sorta.. grew up watching toy story. I was a kid when I watched the first one and now I'm almost on my way to college, just like Andy. It was heartwarming and amusing at the same time. Lots of movies start getting boring after too many sequels, but Toy story 3 is probably the best ending to a trilogy that I've ever seen. ( :
