Took me an age to get back into these series - I found s3e01 to be a bit slow, but it really picked up with the 2nd episode and I'm in and hooked again.
I'm really enjoying this series, but I'm also recognising that the biggest weakness with it is the Matt Murdoch character - he's the least interesting thing in this series so far, and arguably in s2 as well. I think that's a criticism that certainly applies to the Iron Fist series as well, and to some extent to Luke Cage.
I'm only into ep5, but so far... yeah. The only reservation is that you get to expect him to be so machiavellian that it kind of signposts some of the twists (the inciting incident around his being relocated, for example (being vague to avoid spoiling) - as soon as I saw that, I thought "set up")
Finally finished it - like all the 13-episode Netflix series it did drag a bit in the middle, but overall it was very good - maybe not quite on a par with the Punisher bits of the 2nd series, but certainly way better than the Elektra/Hand parts
