One of the most soulless movies I've seen in a while. It feels like all the characters just go through the motions, without ever getting me even slightly emotionally involved. Heck, even the action is dull, and goes on for too long without actually ever doing anything new. The humor that was great in the first one is overdone and lame in this one, and the story has a ridiculous amount of holes and silly moments. The film just has no focus, and even the otherwise impressive effects are misused and totally lacking the wow-factor.
When a summer action blockbuster actually bores you, you know something is wrong.
In a sentence:
A dull, overdone, heartless movie that isn't even really entertaining from a "I like seeing things blow up" perspective.
