Really good watch, would watch again, and can recommend.
It's Will Smith fighting invading aliens, and Jeff Goldblum being almost annoyingly smart.
The alien aspect of the movie and the story are all great, but there is also a lot of humanizing scenes to keep the audience reminded of for what the Terrans are fighting. I'm sure there is a supercut version that reduces the movie to 45-60 minutes of good old alien fighting and investigation, but it's nothing that's actually worth skipping.
If you're into alien invasion / apocalypse movies, then make sure you put this on your to watch list.
