Some of those are the same people who claim that Floyd Mayweather Jr. is a boring fighter. Roman (in his Tribal Chief character) doesn't do a bunch of flips & dives in his matches, but he ALWAYS tells a compelling story.
Another thing that Roman does very well is making his title challengers look like credible threats (and not just by letting them kick out of a thousand finisher's either). Guys like Cesaro, Sami Zayn, Logan Paul, and Daniel Bryan all looked like killers when they faced Roman. There's a lost art to making even a "weak on paper" look like they belong in the main event while still looking like they're not quite on the champion's level.
Guys like Roman, Lashley, Gunther, FTR, Bryan Danielson, and a few others know how to tell a fantastic old-school in-ring story while still incorporating the theatrics of modern wrestling.
