I liked episode 2 I guess? And the ending of episode 4 was neat (but didn't have anything close to the impact on the last two episodes as it should have), and I guess the final episode was better than WandaVision's?

Mackie and Stan do well with what they're given, too. The show is at its best when it feels like a buddy movie between them- they have good chemistry. Russell's character is also interesting, but they don't utilise him to his full potential.

And I guess there's potential to do interesting things with some of these characters going forward?

That's probably the most I can say when it comes to positives. For at least a good half of the series, I found it pretty tedious to get through. Lots of the action scenes were too ambitious for the show's budget (just give us one or two really great action setpieces rather than like 10 that range in quality from decent to inept). Episode 3 is the low point of the show- it's packed with really lame, poorly shot action and a plot that makes no sense (the worst of both worlds).

The show looks pretty bland, and the editing is sometimes atrocious. Writing is disappointing too, and the pacing is strange. Sometimes things feel drawn out, and at other times, things happen too quickly.

Probably more subjective but so many of the characters here I didn't like, too. I know Zemo is popular, but I didn't enjoy him here (nor did I in Civil War, really). The other villains are also among the worst antagonists I've seen in a Marvel film/show so far. Same goes for Sharon Carter... actually, I guess I dislike all the characters who are either villainous or morally grey? The show just doesn't handle those kinds of characters well at all.

It might be my least favourite thing in the MCU so far, and while it's not bad to the point where I want to give up on any Marvel properties going forward (and it's not without some redeeming qualities that keep me from going lower score-wise), it was a pretty bland and disappointing series for me, in all honesty.
