Go! Princess Go! is a charming romp turned drama which I would mark as a must-see for anyone who enjoys dramas. It is a fresh take on the time travel concept, and for the most part, the idea of a man being in the body of a woman is handled quite well. I especially liked how, do to this, it was often the woman who took a more dominating place in the relationship between the two love interests.

Though this drama starts off very light-hearted and seems to lean more towards comedy, there is a gradual shift in tone which solidifies to a complete drama at the end. For the most part, I think the change was gradual enough that it was successful - I could take the ending seriously...for the most part, but I will get to that later.

The Good:
Lighthearted comedy
A fun watch
A unique concept
Has some very heavy parody elements and some meta humor
A unique and enticing romance

The Bad:
Pacing - this show is all over the place. At first, the pacing is relatively consistent but then it begins to drag towards the middle, hits rock bottom, before picking up again.
Sometimes the comedy doesn't quite fit. Remember how I said that the switch in tone was handled well, for the most part? Well, when the tone doubles down, it sometimes falls flat on its face and ruins the mood. Doesn't happen too often, but often enough to be noticeable.
THE ENDING. I can't explain but wow. There should only have been 34 episodes in this series. Just... this is my main qualm with the show. There is nothing worse than having a good show with a bad final episode. And as for which alternate ending is best? I would vote the first one.

Conclusion: Watch it. It's fun, if a bit long, and really enjoyable if you get past all the body humor, haha. The nods towards drama tropes are so much fun to partake in, and the parody aspect of the show is done well and genuinely funny. If you were on the fence, definitely give this one a try!
