The Great Quaalude-Ape.
Look good? yes it does.
technical marvel? Yep.
move right? uhm...no.
the under water feel like as was mentioned before is far to exaggerated and constant.
the first thing I did after watching this is go look at some real chimp footage.
and they are ALOT more spastic and twitchy than this guy, yes they move slow a lot of the times, but it is broken up with a lot of fast tick and twitch type movements.
this one looks like he should be smiling and saying "dude" a lot..
not to mention the suicidal tendancy's with the gun in the one shot..
personally I found that to be pretty "uncanny" as well.
