Well I feel like they finally found their footing. These last 2 episodes were the best in the season. This episode is my favorite with episode 5 being my second favorite.
The plot is so wacky and fun. I loved seeing a Zoidberg and Bender centric episode. We don't see them interact that much and they have alot of chemistry. I would love to see more of them in future episodes.
I love how this episode is about time travel. Bring 2 things I love, time travel and Christmas specials. There are some relevations in this episode that I think are fun.
It was cute seeing fry be able to go the professor and cubert and also leelas family for Xmas. It was sweet seeing Amy's kids again and I love how everybody is having fun. It's a silly fun episode and I'm loving every second.
Also really nice tribute to Coolio at the end.
Overall this episode is amazing, there's not much that I could say i didn't like because it was genuinely really good.
