Me myself i, Sliding doors and The Family man

I think all three 0f these films are very good and quite similar. Do others have opinions of these three movies? I remember this one as being excellent and it came before the other two, HOLLYWOOD films. I think all three were quite good but I would love to see this one again. I like the idea of films where the protagonist gets to see a "glimpse" to use the term don cheadle used in the family man. Any other movies like this come to mind?

I know , I know , Its a wonderful life is a fantastic movie , one of my all time greats but it is not in these vein. The other one that comes to mind is the Jim Belushi one where he hits the homerun instead of striking out and it changes his life. Cant recall the name of that one at the moment but I never saw it in its entirety and I think it was probably average anyways. What do you all think about these three: Me Myself I , Sliding Doors and Family Man?
