Yea, I have little problem with snowboard cross, except inasmuch as unlike ski cross there isn't a true analogue to the 'purer' Alpine discipline, and I wish there would be a real snowboard equivalent of the DH to bring it prestige, but I also appreciate the potential difficulty with that.
In all actuality, for all the slating I give it, I don't have a problem with Big Air, Slopestyle and all the other X Games stuff... but I believe it to have its place, and that place is the X Games, and not the Olympics. The IOC in both Summer and Winter Games seems to be pushing these X Game concourse events (often, like with the cycling, at the expense of more traditional disciplines) in an attempt to appeal to a younger audience, but for the most part what appeals about those events to their audience is not the competition, otherwise the X Games would be a much bigger TV draw. As ever, those events are cool to watch a compilation of tricks with a thunderous energetic soundtrack, like being trapped in a 90s MTV time warp or the Tony Hawk's Pro Skater games, but the competitions are marginal at best in terms of their reach.
Another thing I think of as an element is the gear. Alpine skiers, Nordic skiers, ski jumpers, athletes, cyclists, swimmers, these sports all have specialised clothing that companies and teams invest a lot of money in to eke out the smallest benefits of aerodynamics. The costumes are calibrated around saving vital time or maximising distance. When I'm watching Aerials and the competitors are wearing hooded coats and salopettes, it doesn't feel as much like elite level competition. That's purely a 'feel' thing though, and others' mileage may vary.
I am by and large opposed to judged sports (at least where the judgement is the totality, obviously something like ski jumping is an unusual case, and it's one of the ways to try to balance out conditions so that wind / gate etc. can be accounted for and competitions held safely) and would gladly see all of them expunged from the Olympics, but I do think sports like figure skating, gymnastics and diving are traditional and ought to be grandfathered in.
