jsut been to see it. the best thing i can say about it is that it wasn't much worse than i expected it to be.
at one point you could see the wires that were enabling the rock to jump really high, the first-person scene (which lasted about 10 minutes) made me feel travel sick and the monsters were lame compared to the game and just jumped on the current zombie bandwagon.
it wasn't even entertaining in a shit way. oh dear.
