9/10. I thought this was epic, and honestly, this is what summer movies are all about. It knows exactly what it is, and doesn't try to be anything more... just like the first one. You should've known what you were getting when you bought your ticket, and if you didn't, shame on you.
The first one was a pandering, cheesy "B" movie that happened to have fantastic effects and a fresh take on alien invasion movies that elevated it to "A" status. Not sure why anyone was expecting something more this time around. Goldblum, Pullman, Hirsch, and Spiner were all solid as ever, and the possibility for a third movie (and an expansion of the franchise) makes me salivate.
A lot of people need to take a deep breath and remember why they go to the movies. Especially ones like this. It's big, dumb, fun, mindless entertainment. Stop being pretentious and complaining about cinematography and casting and script issues and plot holes. Watch the big, fun movie and enjoy it. Stop over-analyzing the dumb alien invasion movie and have some fun in your life.
