He really is. When they implied him to be superior to Barry, a lot of fans went berserk. Majority is indifferent after his character development, but he is far from fan favourite. There is a reason why he is not highlighted in Barry's absence even when that should be the case.
I also saw a lot of people wanting OG Wally to appear as an AU counterpart as well. Add on actor's terrible delivery and I don't know how one could expect him to outshine cartoon versions.
