I usually dont see anything....though having started maya in the last year I am noticing more and more...though some of them are also just "WTF?"...like RE5 which I watched yesterday...the dude takes off in the plane to get to Arcadia..when you see the plane on the ship...its crashed..yeh..BUT there are no skid marks etc and I pointed out to my son..."the plane is facing the wrong way"...he said "huh? I dont get you Dad?"...have a look at the plane the dude (who cant fly really) has somehow dodged the bridge and landed in a bunny hop fashion.

I think you will find a lot of those in the Star Trek TOS as well LOZ LOL...funny stuff
