The weakest of the opening three seasons of 'Luther', but that's not to say it's a bad one - the opposite, it's a very good third coming.
Not much more needs to be said about Idris Elba, he is yet again the key to the show and gives a hat-trick of superb performances. As for those around Elba, Warren Brown continues to be enjoyable as Ripley, as do Dermot Crowley (Schenk) and Michael Smiley (Benny). Nikki Amuka-Bird continues too. I still like her as an actress, but man does her character continue to irritate - Gray goes full-on hypocrite this season. She's joined by Stark (David O'Hara), who is like a Mini-Me in terms of what I found annoying about Gray in S2. Stark should be one of those characters you love to hate, kinda like Alice (Ruth Wilson) in the earlier seasons, but he's just simply irritating to see - at least to me.
I found myself unappeased with a few of the storylines here, which is something that I didn't feel across S1/2. It's not that any of the plots are disappointing or negative, they just unfold in a way that allows me to be questionable about them. The final episode is fantastic, but the one or two before aren't as great as what we've seen before from this show - probably a victim of its own success more than anything, given how utterly brilliant the preceding load of episodes have been.
I want to make it clear - I thoroughly enjoyed this when all is said and done, despite some (pretty minor) issues as mentioned. No matter what, I'm buzzing to watch the next two seasons.
