While I still liked it overall and it had some fantastic episodes of it's own, I too felt that the Capaldi era was a bit too harsh/serious. Whitaker's series gets bad buzz, but I really enjoyed her take on the character and just the vibe in general. It was very refreshing and joyful (with it's own share of serious moments).

So far, Gatwa's has been mostly fun. Probably a bit more camp than I'd prefer, but it's definitely still good, imo. I'd recommend checking it out if that's what you were missing from the Capaldi era. And be sure to start with the 4 episode series of specials if you're going to skip Whitaker entirely (though I wouldn't recommend that, personally).
