It's alright.  It's a decently fun heist story with Eleven charmingly leading the way.  None of the UNIT characters or villains really stand out that much.  Nor does Eleven's Eleven have any big, memorable heist moments.  It's barely an actual heist at all, more a story carried by Eleven a bit, who is a very fun character that really lets Mark Bonnar throw a lot of performances into once role.  And the heist itself is just creative enough that I was never really bored, either.  Not much stuck with me, but there's fun to be had with Kate, Osgood, and Jacqui that it makes up a bit for the lack of any real heist content.  I liked the concept of Eleven recruiting a bunch of criminals but the execution of that idea felt bare bones at best.
