Parkour is becoming rather cliché
But you don't see me complaining!
I'm extremely happy many recent movies include it. Not because I am that into it (although it is very, very cool - had I discovered it when I was younger, I would definitely have gone into it, just to play ninja), but it is very much a product of this time, one of the things I will associate the '00s and '10s with. Years from now, looking back at the movies from this era, the sight of parkour will make me extremely nostalgic. I appreciate that. It will remind me of what was likely a better time (or so you always think).
I introduced this non-sport to a friend of mine years ago, and he's still performing parkour today, 5 or 6 years later. Heh, he even mentioned me in an interview he did in a newspaper. Not by name, but he still acknowledged me. Chances are he would eventually have discovered it himself, but it still makes me feel really good about myself. I showed him something he has practically lived for this long, and seem likely to do for many years more. It will always have been a huge part of his life, and I helped with that.
