These movies are a guilty pleasure of mine.
This dosen't qualify as a Michael Bayish movie IMO, simply because as lacking as the plot was they actually afforded an effort to create one, which instantly dislocates it from being near a Bay type movie IMO.
I enjoyed it a lot, although I really get tired of the 1st person shooter perspective on these, it's fun for short bursts but when you get a long long scene of it I just get disoriented by it.
I liked the idea that we could just fight something without it being human to human conflict, love the alien invasion theme, they should make tons more of these and do them better.
It's just Independence day redone on the ground, the best way to do these would be if someone wrote a very good book series that started from invasion then chronicled the whole war from start to final finish.
You need some more time to develop characters and set the scene plus develop a really good plot that makes sense and if you really could do that there's some wonderful possiblities for showcasing mankinds higher qualities I think.
There are book series like this, but I've yet to see a really great one.
V was a pretty go try at one, then that one they made that Travolta movie thing out of... oh my...
I'd like to see a good balance of actual technology, as in rooms full of scientists trying desperately to decipher the alien technology coupled with on the ground action, coupled with the story of cooperation and perhaps using a smidge of highlighting some earthly villians and how obviously destructive their behavior is when put into the context of a joint effort.
Lots of stuff you can do.
Want to see it from many different angles too, would be great to do a Star Trek like theme where you tossed in representatives from all the areas of earth and follow their stories as they come together to defeat these things, and first they have to lose, that's key and so is a hail mary shot to win.
