This BBC miniseries about a not-too-distant future where Britain is a surveillance state had the potential to be very good, but it is not. Still Cumberbatch acts his face off wherever he goes, so if you're a completist, you should give it a shot. (At the very least, it has a super hot smooch to recommend it.)
