I share the same opinion regarding Underworld as the previous comment.

I sat through the 1.5 hours of this movie wondering what this story was all about and more importantly why the author and/or director had made certain decisions for the plot. On the whole I found the movie to be unbalanced, consisting of strange sub-plots which (IMHO) actually had nothing to do with the movie. Furthermore, when writing a thriller I'd say you want your viewers to wonder about the story and not about the way the story is filmed...
