Pretty simple idea, just say what the last film you watched was and rate it out of 10, then if you like add a short comment - save big reviews of new releases for the discussion threads about them.
Heres my latest:
Unknown - 6/10 - disappointing, i think the disc menu gave too much away.
Sucker Punch - 7/10 visually beautiful and more understandable on second viewing, unfortunately i watched the theatrical version as the discs were not labelled with which version they were - i'll give it another go another time.
Flags of our Fathers - 7/10 I probably would have liked this more if it wasn't cropped to fullscreen for tv
