Omen 2
Hmmm, I disagree. Omen 3 was a travesty but Omen 2 (imho) stuck to the original premise that he wasn't to blame and that there was just an inevitability about his rise.
I also clearly remember the entire cinema holding their breath for about a minute, until we all let out a collective gasp, at one point. Anyone who has seen the film will have held their breath during this scene I think.
The Omen, the remake, goes down as one of the most pointless films ever made. They even went to the extremes of finding people who looked just like the ones in the original.
