So is it worth watching?

People on here say it's highly underrated, then some say it's horrible, then rotten tomatoes gives it 68% which is pretty decent for a space movie but the trailer is absolutely horrible....so should I watch it? How does it compare to "sunshine" or "mission to mars"? I loved sunshine and enjoyed mission to mars.
