It's got the trademark Mamet stable of actors (William H. Macy, David Paymer, and lesser known familiar faces like Tony Mamet and Alexandra Kerry...but not, oddly, Rebecca Pidgeon this time around), the reknowned Mamet dialogue, but, somehow...it's missing something. There's a whole dead spot in the middle that just feels...wrong somehow.
It's an engrossing film, but you just get the feeling that it could have been more.
One nice thing is that, in this film, FakeBoston™ is actually real. There's a scene in Charles Street in which you can recognise buildings, there's a shot of the Citgo sign, and there's a news reporter broadcasting live from Harvard Square in front of the Out-Of-Town-News. There's also Copley Square, the Charles River, Harvard's football field, the new bridge...it's easily the best part of the movie, at least if you happen to live in Boston.
But if you don't happen to live here, then you're just kind of stuck with the whole plot on its own...and that might get a bit dull after a while.
