4/5 because the show maintains a consistent tone and suspense, some might argue there should have been more in the 6 episodes, but this is a show and not a movie. The show overall does great with building and establishing obi wans character and depicts the Jedi as they realistically are, weak and helpless with some rusty abilities.
Some may argue the show depicts Liea and other characters as too smart but remember plot wise these characters including obi wan die of their own arrogance and the dark side prevails, which this show highlights while the light side barely survives through this.
The level of suspense is good, though there could be more character building with the other inquisitors but seeing how they are not the main point of the show it's not too important so another reason for 4/5, but they still should show them all in action at some point and more to get a 5/5.
Some compare the main inquisitor to a character who is thrown away, but remember, Sidious technically didn't even know one was vaders apprentice and that involvement they had, so why would a character under the radar be relevant to the empire anyways when he dies? Unless he somehow survives.
The show does lack confrontation with Vader to Kenobi and the inquisitors because they always barely let him escape, so perhaps we can see more harsh confrontation in the next few episodes but if not then 3/5
