I know Finn's reign was mediocre. His initial introduction was full of hope and promise! He looked great with Itami, especially in the tag vs the Ascension. The demon gimmick was teased as an entirely different character. He looked and felt like a star.
His feud with KO had Owens cut a better promo on the crowd at Full Sail (a much more interesting character) than Balor. The whole thing was a bandaid because Sami got hurt and Owens got called up extremely quickly which meant it felt rushed and out of place. His matches were ~fine~. His never cut a single memorable promo. His character was white Apollo Crews who dressed up in increasingly cornier bodypaint and fake dreads that he put together with stuff he found in the dumpster. He was constantly overshadowed by the women's division where the real emotional, true championship feuds were occurring. His TV matches revolved around headlocks and a very stale closing sequence. His finish sucked. He was infuriatingly more compelling on social media and at house shows than on TV I paid for.
There was no progression in anything - his feuds, his character, his in ring. It all stayed a very safe, samey WWE approved speed. Gone was the cocky charisma of Prince Deveeh-to~, the Real RocknRolla, relegated to few moments in a TV entrance. Instead we had "face of the company in training" Finn Balor. He spouted marketing slogans during his promos. I never felt like he was ever emotionally affected by anything that happened to him or around him. The funny thing is, he arguably isn't the true face of NXT as Bayley may have supplanted him as the babyface everyone loves and associates with the promotion instantly.
And yet he quietly presided over the male side of NXT as it exploded into big arena shows, countrywide tours, international house shows, actual merch, reality shows and much more. It an odd way he was the right guy to slowly subsume the developmental system into the corporate sea of WWE, a new revenue arm, a new social media presence and a new kind of fanbase. Sadly (and this is not in any way an excuse) Finn Balor, NXT Champion on TV was just ok.
Yet still, I really really like the guy. I will watch everything he is involved in. I am unabashedly excited about him on the main roster. I think his potential to be a big star is sky high. I'm not sure why - maybe its a combination of knowing he's perfectly adapted to the WWE style (see constant comparisons to Cena) and that I recently finished up watching all his NJPW run and I KNOW there is more there to it.
It's gonna be interesting.
