There was almost no point in bringing back original Wells if he's just going to relive his glory days in a Groundhog Day loop. What was the need for him? Couldn't Barry have figured things out for himself while at Iris's side when he emitted the spark? And they are really leaning into the whole "we are the Flash" thing that Iris said since it seems as if she's the one who can give him his speed force back and completes him. I don't mind Ralph leaving but they should've kept Sue around. She's far more interesting and the series could've done with someone like Natalie Dreyfuss. Why do we need Allegra and Chester? Eva has been a boring villain from start to finish. How does she suddenly turn over a new leaf at the end and is allowed to escape to the mirrorverse? And how is she going to start a new world there? Who else is there with her since she claimed she was so alone before Iris arrived? It's not like there are other people to interact with unless she has kept some people prisoner. And if she goes back to the mirrorverse, isn't the itchiness going to come back? They didn't give her any skin cream before she left?
