Unfortunately I have the same problem with season 4 as I did with season 3. Everything Barry related I mostly enjoyed, but everything related to the side characters I hated yet again. It was either boring or really annoying. My biggest gripe was the time jump though, out of place, unexplained and unenjoyable, I couldn't believe for a second that Sally would have a baby with Barry, very silly.
I'm disappointed, I really enjoyed the first two seasons but the last two have been really poor in my opinion. Shame
I'm glad I don't have to suffer f***in Sally anymore though!
