If I have to choose, I'll go with the original, but I really like them both a lot. I have to respect the original more just for taking the basic Rosemary's Baby idea and really running with it, turning it into so much more... the sense of implicit destiny and almost mythic grandeur of the settings in Rome, London, and Jerusalem... the haunting soundtrack... just that feeling of unseen forces and entities controlling our destinies, just out of sight... it really wigged me out, the first time I saw it.

I like Omen 2 also, however. I thought it was really interesting how they set things up to suggest that Damien's life would go in a military direction. That whole school was a military academy. And, even more, they showed Damien personally as being unusually competitive within that environment, like when he makes Mark race him around the grounds. I really think they were planning to take the franchise in some kind of a military diretion, maybe leading to some kind of Armageddon type of clash in the end, but then they decided to make Damien more of an evil diplomat, in Omen 3 (which I also like(mostly)).
