The critics lambasted this movie, so I didn't go to see it at theaters. Instead, I bought the DVD off of eBay a few weeks ago and only watched it last Saturday morning, 4:00 a.m., because of sleeplessness. I was pleasantly surprised at how funny and entertaining it was. I hope I didn't wake the neighbors when laughing out loud in my recently completed "man-cave" (enclosed the patio). Definitely worth renting or owning if you like comedy with a twist of sci-fi. Lots of dialogue references to other sci-fi movies. Also, a cool ending.
