Despite it's flaws, and I will get into these very soon, Focus is actually a lot of fun. It's not a film that breaks new ground, nor is it a film that's all that smart. But what it is, is entertaining. It's a short, fast and enjoyable flick that doesn't really require much effort to watch. While filmed graciously and directed even better, Focus, unfortunately, isn't a film I see myself coming back to.
The film's performances are the least of its worries. It's the predictability of it all that this film should've been concerned with. Focus sets out to be the next great con film, and like all great con films, it's got a few tricks up its sleeve. Very predictable tricks. As the scenes are played out and the cards are put on the table, it's not all that difficult to work out what's a con and what's real, but by the time the third act comes out, I didn't really care either. I just had fun with the film, predictability and all.
Neither one of these halves are bad. In fact, they're both very entertaining, but neither one is fleshed out enough to last. It's almost like a lazy two part tv pilot, the first dedicated the setting up the plot and then the second disregarding the first episode's plot entirely, but like I said, at least the filmmakers made it entertaining, and for that, I'd say this film is worth a watch. Or at least a rent.
