STarted out the afternoon watching POSEIDON on HBO-HD. Not nearly as effective as the 1972 version for my money though, of course, it cost hundreds of millions more to produce. To be honest, I don't think the actors were nearly as personable a bunch as in the 1972 version. I actually found several of them very irritating and wished them ill, not what the writers and director would have wanted the audience to feel, I don't think.
I'll stick to the original version as a guilty pleasure. I don't really understand why they felt the need to remake it anyway.
