So because TV shows tend to get cancelled if I watch them in real time, I only just now got around to watching this series. I'd walked in on an episode occasionally when someone Else was watching it, but never really sat around until now. I'd already watched Agent Carter, but aside from that and the Films, that's all I have for exposure to the universe.
It started out pretty decent and I think I caught the handful of movie tie-ins, but after a while it very quickly felt isolated from the rest of the universe from my perspective. Not as bad as the latest itteration of Doctor Who (I swear to god they're throwing darts on a board for that one), but it started to feel rather "out there" and the last couple seasons started to feel forced. Especially the last season where they seemingly left episodes without real ending at times. IDK, TV always felt less focused than film to me for many shows, so I can't say any of it is completely unexpected.
The biggest take away I guess I have is that the series overall felt less cannon because I had a hard time seeing how what they had been doing wouldn't have been picked up on the radar in the films. Consequences that they created seemed to have little to no bearing on the expanded universe.
