Mr. Perfect is one of my five favorite wrestlers of all-time, and I thought he was great either way. There was something cool about that face run, because it felt like finally the rest of the fans were catching on that Curt Hennig was truly a talent worth cheering for.
The one negative thing about his face run was that he couldn't be all-out cocky like he was as a heel. He wasn't that toned down, but I would have liked to see him as full-throttle full of it as he was in 1990.
So maybe I slightly preferred Hennig being a heel, but all-in-all I didn't really care; I was just glad to see the man wrestle. During that time he was Ric Flair's executive consultant, I was pretty upset that he wasn't wrestling; when he came back to replace the Ultimate Warrior as Randy Savage's partner against Flair and Razor Ramon, I was f'ing stoked. It was truly an honor to watch Perfect work--one of the greatest ever.
As an aside, I met Mr. Perfect at a hotel/restaurant in Milwaukee in 1991, about a week before WrestleMania VII and his match against the Big Bossman. I just happened to run into him walking in the lobby. He was a heel at the time, but he was the nicest guy to me (I was 12 at the time). He gave me an autograph and we talked for a few minutes about wrestling. He had no obligation to even give me a second glance, but he took the time out to talk to me and truly make me feel important. Curt Hennig was a great wrestler, a great man, and I miss him very much.
