So I just got out and I really liked it. For those worried that they were going all grimdark don't worry, the tone is exact same as the first movie: light-hearted but serious only when it needs to be.
There were some changes I didn't like though:
-Connie is never once mentioned, so people who remember the first movie might be scratching their heads
-Rhea or Mars are never shown :-(
-As mentioned above, we never the President taken before the queen and the queen is simply killed by the hijacked alien fighters, not run over by the school bus
The movie moved fast and it really leads to believe that all the above scenes were indeed filmed but cut due to pacing issues. I really look forward to a extended/director's cut.
Overall I'd give this a 7/10. I really REALLY hope this movie does well enough got sequel.
