Fifth Element rocked. Most recent bad ones I watched was Meet the Spartans, Coral reef adventure IMAX I actually had to turn volume off to enjoy the movie stunning reef footage, but atrocious dialogue.
Here's one: We're worried about the lack of sharks along this reef because it may mean this part of reef may be unhealthy. Me commening: Well did you look over there?
Idiot (I mean expert): Oh, theres about two hundred sharks (same reef, diff area) in this valley; looks like they're mating. It's very dangerous for us and we must not let them think we're sharks. WTF??!!
Then there's the part about the "expert" diver getting the bends and almost dying; and instead of the normal depressurization treatment, he used high oxygen treatment...didn't work, so he used the depressurization treatment, and me yelling why aren't you in a depressurization chamber? R-tard.
