ow ow ow.... Given that both involve more plot-holes per minute than an average MST3K flick, is it really worth discussing which one is slightly less flawed???
(Ok, nerds, before you start flaming me, yes, both were entertaining. But, I'm a fucking physicist. I have very high standards about that sort of thing when you start talking about realism; expecting suspension of belief is fine, but trying to explain bullshit physics of fictional universes just makes the bullshit smell that much more pungent).
