Edge of Tomorrow

What if Groundhogs Day was an action, sci-fi, movie (surely based on a video game) instead of a comedy? I actually had a good time watching this movie and you will too as long as you don't expect too much from it. It is about a reluctant soldier who gets sent to the frontlines during the final showdown between humanity and some bizarre alien invaders. For reasons that will be made clear if you actually watch the movie, every time he dies he restarts the day, and it is up to him and the hot, tough girl / possible romantic partner (and some assorted misfits) to figure out what is going on and how to save humanity.
