Summer blockbuster season is upon us. And a lot of this year's slate end with the suffix "2", including "Grown Ups 2" (which scored an amazing 6 percent on review aggregator website Rotten Tomatoes), "Red 2", and "Despicable Me 2". Then there's "The Hangover 3", and "Iron Man 3", not to mention "Fast & Furious 6".
