To me it didn't matter in which category they categorized this movie, it's a bit of all of the genres mentioned without any genre being more represented than others. The story was interesting enough to keep your attention at all time. To me it was well thought of, probably the best thing about Becoming. The acting wasn't bad but not the greatest either, it had it's ups and downs. The cinematography wasn't flawless, it made it look like it could have been a TV-movie at times. There is some suspense and the story is innovative and good, all reasons enough to give it a shot, just don't expect a masterpiece.
