Movie was Good, ending not so much

Rating: 7/10 (28 October 2005)

For once i would like there to be a movie about Alien Invasion that doesn't end up with a simple and fast ending that involves the stupidity of aliens.
Independence Day: A human-made computer virus infected their advanced system and all shields were gone (the aliens might wanna think about getting a firewall/Norton Anit-virus set up).
Signs: Water ended up being their instant-dead serum (they might wanna scan a planet before invading it and realizing it's 70% what kills em)
War of the worlds: the air and food killed them (they might wanna fire the person who headed up this supposedly 1 000 000 year attack plan for not having the time to figure out that stuff would eventually kill em)
Although overall these movies where good, i'm still hoping for a movie that has a smart plot in stead of a simple and fast one. but can imagine it's not easy making such a plot.
