Nnnggghhh.... I dunno, other than some modern high-budget Special FX and filming techniques, it doesn't look much different than many other "Aliens from another planet invading us" type of films that I've seen before. I'm sorry, but other than updated SFX I don't see much that's really original or any creative twists that are pulling me in with any great interest.
Not to get on a soapbox and start a long, rambling post, but this is another sad example of how recent filmmakers don't typically come up with new or original ideas for movies, they just re-mix and re-hash old ideas and redo them with updated SFX, CGI, and eye candy. Oh, that and they typically over-glorify many of the scenes in many of these flicks with an over-dramatic soundtrack (choirs, violin/string sections, and a few select songs from recent crap-artists that they have deals with the music industry to include as part of over-promoting them - most of which really have little to no musical talent), all to OVER-do the drama in unoriginal, boring scenes that really aren't all that exciting or tear-jerking in the first place.
I've just seen so much of this in recent films lately.
I could also go deep into the awful practice of ruining classic, well-known films from the '80s and '90s with sh*tty remakes - or worthless sequels - But I won't start that here.
BTW, Hertzilla is right, it does indeed seem USA-centered. I wouldn't be surprised if the plot involved one or more Americans saving the day in the end, but not before some random nation overseas gets blown away to ruins first, as part of moving the plot along (with the idea in mind that they have to have some kind of tragedy at some point, complete with an over-dramatic point in the story when everyone who didn't die reflects on the ones who did).
Oops! Did I just give the whole plot away, and spoil it? Sorry, my bad...
