Same. I consider Bloom and Gloom and Appleloosa's Most Wanted to be the worst of S5 but they are still both underrated and people don't appreciate them for some clever things in each episode. Castle Sweet Castle is also very underrated.
Amending Fences, while good, is also an overrated episode.
I completely forgot about Princess Spike. It would be in the bottom three but Appleloosa's Most Wanted executed the interesting idea badly in the beginning. The end moral was great and it was a nice look into the CMC's future destiny but it was more badly written than PS.
