I think season 3 could have been better if we hadn't had a speedster big bad for the third consecutive year. We needed a break! Not to mention that Dr. Alchemy was actually a cool villain in its own right imo. Sucks that it was more of a bait and switch for Savitar. Also, I hated how they used Iris too. Like I knew right off the bat the show didnt have the guts to kill her off... so dangling her death for so many episodes was dissapointed.

As for Barry in season 4... from what I read in previews... they are modeling his return and premiere after DC Rebirth and the way in which ginger Wally West came back.
