I find the relentless stoppages in NFL and NBA excruciatingly dull, and the sports at best so-so to watch, but hey, that's just culture talking.
Seeing the Broncos live a year or two ago was quite an amazing spectacle. There's a lot going on that isn't the sport: horses, parachutes, fireworks, cheerleaders in skimpy outfits. Real Colosseum stuff.
No one can objectively demand that others find Test cricket interesting if they haven't been raised on it.
