I immensely enjoyed this season. Dan Stevens was a fine replacement as Korvo. He captured the character's personality, demeanor and attitude fairly well, and his distinctive voice helped Korvo stand out more from Rick Sanchez. Although I probably wouldn't place season four on the same tier as its direct predecessor, it contains far too many wonderful aspects to dismiss. The writing is still hilariously inventive, the characters are charming as ever, and both the Wall and Silvercops storylines remain thrillingly epic. Plus, the Solars really felt like a genuine family this time around. Jesse and Yumyulack have always been my favorite relationship in the show, and this season contains a few sweet moments of bonding between them. This batch of episodes is stuffed to the gills with gags, heart and references that range from Hanna-Barbera cartoons to Gerald's Game. I highly recommend it.
