Call me crazy, but I actually like Season 5
I rewatched Season 5 recently and started Season 6 again, and I'm noticing more that the show gets janky with Season 6 rather than Season 5. Yes, Season 5 is a lot more lighthearted, but it's got great episodes and an overall great arc to it. With Season 6, I really wish that Chris's antics was more because he had to protect his secret about being a reincarnation of Prue rather than turning out to be Pipers second son.
