I had a pretty great time with _Tag_. Maybe that's because I went to a nice theatre (which I haven't done in a while) and saw it with a couple of close friends on a very nice day, but I rather think that it's primarily because of Jeremy Renner's character. The way he's written, acted, and shot, are all pretty much flawless. Off the strength of him alone, I could probably send you out to see _Tag_, but there is a Hell of a lot else to appreciate about it too.
_Final rating:★★★½ - I really liked it. Would strongly recommend you give it your time._
