Why the movie didn't work....
The title of the movie is Helena from the Wedding, so you go in with expectations that Helena is going to descend on the scene and be this woman who has it all: beauty, brains, a great personality, refreshing, etc. But I honestly didn't find Helena to be that great, and certainly not so great that a man would consider cheating on his wife for.
I think of a movie like "Beautiful Girls", when Uma Thurman comes into the movie and is just so awesome and the perfect woman basically, it's no wonder everyone hangs on her every word, and no wonder men are desirous of her even if they're in a relationship.
Helena = boring = yawn. Yet her character is the title of the film. Her character is the one that's going to come into the picture and inspire all the men to be mesmerized by her??? Nope, didn't even come close. Maybe if they cast a better Helena who brought some life & lightness to the movie, I would have liked it better overall. I was actually more interested and drawn to the woman who was pregnant!! lol.
