I watched it recently too. There were some obvious holes in the story. For instance how come the aliens can jump onto and off of a 10ft roof, can run amazingly fast, but can't avoid a guy with a baseball bat? Trees & forest, corn & stalks, I know. But for me it broke the involvement in the story that had been developed. What I was really hoping for was that the aliens would not have been shown at all. If they had remained shadows and sounds, that would have been much more effective. Instead we had the cliched green men with funky eyes.
Anyway, yes it was a good movie. My favourite scenes were when Mel was at the table declaring that he would not waste any more time on prayer, the reaction of his family was perfect. Later he is seen crying saying "I hate you". Yeah, very moving and very real.
