I agree some will find him bland in the WWE, yet you can't call him bad based up on that only. Especially when he's only be given very little to work with. When he's been given more to work with he's proven himself a decent monster worker, better than most on the roster. Another example is I found Bryan to be very bland during his face US title run, yet I didn't call him a bad wrestler as he was working with the poor details he was given.
Also why should every guy wear the same thing? Show, Henry, Clay and Ryback would all be running around in similar attires so adding another to that increases the generic feel of it.
