I thought there were great bits, but it was a bit more hit and miss than the last two seasons. The 'Monks' trilogy was a bit misjudged as they used up three episodes on a story which just wasn't that brilliant.
The 'Vault' storyline was a bit of a damp squib as its contents just weren't that surprising.
I thought there were a lot of good bits though. Really liked Bill. Really liked the idea of the Doctor teaching at a university. Nardole was surprisingly cool.

Thin Ice was great. That punch was hilarious, as was 'no sh**!' Oxygen was also pretty great.
The finale was great. Really great use of time dilation as a plot lot device and both the returning individual villain and class of villain worked really well.
So yes, flawed season but good overall.
I might write a post with my favourite quotes from the season as there were some great ones.
