'Supernova' is a space rescue mission movie that ends in horror. The effects are horrible and the overall movie is horrible, which makes you wonder how something like this even gets made. The movie has three directors listed, including Francis Ford Coppola. He may be good, but I don't necessarily trust his expertise in the sci-fi genre. It's kind of like Michael Jordan going into baseball. Just because you're good at one thing doesn't mean you're good at everything, buddy.
I can't help but feel like this is more of a "watch it for free on SyFy network" type of movie. This isn't something you want to pay ten or fifteen bucks for. I also describe it as a "clean the house" movie. It's a movie you put on the background while you clean your house.
