Some overall take-aways about Episode 1-5 as far:

There is a weird decline in production quality compared to Mandalorian. When watching the Mandalorian I feel like I am watching a movie. Watching Obi-Wan, you definitely feel like it is a TV series.
Disney is very committed to keeping Vader as “the ultimate villain”. He is portrayed as extremely menacing and much more powerful than he seems in the OT. I am pretty satisfied with how Vader is handled in this series. However, nothing so far beats the Rogue One hallway massacre for sheer visceral excitement/fear. I also think force-users being able to stop moving starships is a bit over the top, crossing the line into “super-hero” territory.
Before this series began, there was a lot of chatter around the Internet about how the new character Reva would turn out to be the star of the show, stealing the spotlight from Kenobi in some way and perhaps being unreasonably powerful (echoing earlier complaints about Rey). But this has not happened at all. Kenobi is clearly the star, and Reva is easily defeated with minimal effort by Vader. Reva is not a bad character either. The actress portrays her commitment and desperation very well when she fights a hopeless battle against Vader. The main problem is that Reva is much more interesting once you know her backstory. But the show doesn’t really go into her backstory until Episode 5 unfortunately, so from Episode 1 through 4 she often just comes off as a generic villain.
Anakin (Hayden Christiansen) is really underused. I’m not even a Prequel fan, but I feel bad for the Prequel fans who were expecting more recurring flashbacks showing Anakin/Obi-Wan throughout the series. I was also curious to get a glimpse of Anakin as a young man directed by someone else other than Lucas. But we get barely any footage of this, except for this brief lightsaber sparring in Episode 5. I feel like these flashbacks should have been a recurring thing throughout the series.
