Show
Review - Seasons one and two are absolutely brilliant. Season 3 is amazing, but you can feel it fall off.
It absolutely jumps the shark into season 4. Season 4 is still enjoyable, but it becomes a different type of show.
Season 5 is basically a new show, there’s some really fun parts with all of them living in the 1970s, but so little connection (thematically) to what made the first seasons so enjoyable.
Season 6 is a mess. Its trying too hard to tie everything up, bring back all of the plot lines, etc. in a way that doesn’t really make any sense. By the time the two part finale rolled around, it took me 3 weeks to finally get through it. I was just not into it.
