Let me just say I've seen EVERY episode, so I'm not coming in here upset at the popularity after one or two episodes. The whole series has a big problem with tone. It's incredibly goofy and can be funny at times, but takes itself so seriously it ruins it. There are moments where it also can be creepy and unsettling, but then ruins it by trying to add humor. These are really my only criticisms of part one and two. When part three starts tho it turns into the same thing for a majority of the season. Fight enemy for 1-2 episodes, change scenery, rinse, repeat. This is the same formula that the next 2 parts and is followed for the ENTIRE season. It reminds me of the Naruto war arc and how repetitive that is. How nobody gets bored of this beats me, but these three parts are a majority of the show and drag it down so much. Part 6 changes the formula and I found more enjoyable but I was so checked out at that point I could barely care for anything happening.
