This was one of Star Trek's classical side-line episodes, which often cause a lot of split opinions, but I firmly believe that these side stories placed completely outside of the usual "Trek environment" provide the necessary break from otherwise very serious episodes, and they keep things exciting and different.
Story-wise, I'd say that if you do like these kinds of episodes, you will find the plot very enjoyable. The story is interesting with many fun bits and it's a welcome change to see all of the characters in a bit more "goofy" roles. We also finally got some resolution into the long-running plot line with the doctor's daughter. It was truly very unique and interesting, with an absolutely amazing ending.
Acting-wise, I think it did alright. Even though some things certainly could've been better, I think the characters felt enjoyable for a one-off comedic take and the actors did a mostly great job at portraying their roles.
What's a bit surprising to me is how many other reviews here describe the acting in this episode very negatively. I mean, it's certainly different, but that doesn't make it bad, I think for what characters the actors were meant to play, they really did do a fine job, and I do not understand the huge backlash. I think it was mostly caused just by the general controversy of a different episode, but given the environment, I can't complain about the acting at all.
Watching this episode made me very nostalgic of similar classical trek episodes, and mainly reminded me of the Robin Hood episode in The Next Generation, which at the time had similar backlash for simply being different, but at the same time, it was so iconic and memorable, and simply fun to watch.
We just need to keep an open mind, episodes like these were in almost every trek show, and we should all take them lightly, enjoy the differences and foolishness and just have a laugh, not everything should always be so serious.
