Over at io9 the folks are doing a March Madness bracket on the worst science fiction movies ever. I suggest you head on over to io9 and put your vote in. Some movies are so amazingly pinned together that it is hard to measure how much they sucked because the movie titles are measurements of suck themselves.
Waterworld v Batman and Robin
How do you pick between those two? I would reason that Batman and Robin was 3 Waterworlds. Then again I could argue that Waterworld was 3 Batman and Robin. I guess there is a 1:1 ratio there so the pairing makes sense.
I picked Batman and Robin because of the Bat-nipples.
