S12: Some great highs, and a few weaker episodes, but generally the season is another good one
6 May 2017 | by bob the mooSee all my reviews

This twelfth season is a little bit inconsistent in its quality – although that feeling is at least in part influenced by the opening two episodes being so brilliant. That said there are weaker episodes in here where everything didn't quite click (the hidden camera one for instance, or the murder-documentary one). Generally though the show continues to get great mileage out of its morally empty and selfish characters all being true to that nature, while also judging others for doing even a fraction of what they themselves would do. Hero or Hate-crime is probably the best example of that in this season since it strips everything away to be just about that type of interaction within the group, but it is throughout everything.

The opening episode confirms a show still trying things and willing to take risks; this approach does mean that something don't work as well, but that is a price worth paying. The focus on race by way of body- swap comedy, but then to also then do a musical is an idea so stupid that I was sort of wincing at first because I thought it was corny. However quickly it won me over by virtue of what it did, and how it did it – and of course how much I laughed. This continues through the season, with even the 'weaker' episodes still producing laughs. The cast continue to play their characters well, and even in some changes they continue to make it work – although it will be interesting to see where the next season takes the various steps here.

Not a perfect season perhaps, but some very strong episodes and generally the season maintains what the show does well and does it in a way that fans will like.
