Skyline looks like it could be amazing, but will probably turn out to be pretty terrible. I read that Donald Faison (Of Scrubs fame) and Eric Balfour (Milo from 24) will be playing the lead roles. Based on the fact that both haven't really done this type of acting in their careers I don't know what to expect from them. I really hope they can pull it off because this has the potential to be a really good film if, as Justinsayne said earlier, they concentrate more on the story than they do the special effects.
