Oh, I think I really liked S3. I think the point where he becomes an MP was a bit shark-jumpy for me, it could actually have been really good and funny if they'd played it as like "of course this manipulative, back-stabbing, murderous, smack-dealing cunt becomes a Labour MP, it's the perfect job for him", but instead they seemed to be going more for "see, he might be a manipulative, back-stabbing, murderous, smack-dealing cunt, but he's a Labour MP so that proves he's really a working-class hero with a heart of gold".
Also, I was a bit sad when they killed Alfie off cos he was a great character, but respected the show for how they did it and thought it was a really good ending for him. But then when they brought him back it was disappointing because it just felt like "OK, you don't need to have any emotional investment in this show now because anyone they kill off might just get brought back to life anyway". And the thing with Alfie saying that he ran Boston now because Tommy had killed about two people from the other Boston gang just felt like they'd not thought it through at all.
Still though, it did have some very good haircuts in, and that's what it's all about at the end of the day.
A lot of times in the last series I kept imagining Gilbert Ratchet from Viz making a historical-drama-production-o-matic machine and then going "shit! I've accidentally knocked the 'style over substance' dial all the way to the top!"
Oh, and is Billy the Rickety Cricket of Peaky Blinders?
