Reigns would've been money had they simply booked him as a Goldberg-like badass, just mauling people, and not saying much. Unfortunately, this is the WWE, and it's like they booked him with multiple personality disorder. One week he's telling bad jokes, the next he's making up awful catchphrases, the next week he's too cool for school, and the week after that he's a "madman". I honestly don' even know what Reigns' natural personality is.
Ambrose on the other hand, even thought as a face he's way too wacky and animated, I still know exactly who he is, nothing feels unnatural, and the crowd has responded in kind. The WWE needs to learn how to let things naturally take course instead of trying to force shyt. Reigns ALMOST had the crowd completely on his side, then the WWE totally blew it.
