Eeeesh.
Yeah, I looked at a "video training" school as well, once. I thought it might be worth it to get their free introductory video and maybe pick up a few additional tricks to supplement my training. I thought, "Hey, if it's any good, I can get some of the other tapes and pick and choose techniques....". Well, it...uh....*wasn't* any good. Matter of fact, the tape became the hit of gatherings from that point on.....we just put the tape in and laughed ourselves silly at the ineffectiveness of the techniques. I realized then (okay, this was like 9 years ago) that learning by video, without any basis in any real art, was not only ridiculous, but also very dangerous.
As for McDojos, they hurt more people than they help. You really do get what you pay for, and even more what you *train* for. I know a couple of people who are low- to mid-range black belts from some of these schools, and after talking with them about martial arts, I realized that they knew very little about MA in general, and their own "art" in specific. Sad. Even sadder was when, as a low-level brown belt (and nothing special, mind you!!), I could match these "dan ranks" in sparring.
McDojos hurt adults, true.....but they are worse on kids. Kids who are exposed to MA should learn a number of things, including discipline, confidence, and respect. However, at McDojos, they learn that they just have to whine and pay money, and they will get a belt next time the test comes around. These fake "black belts" are going to be really surprised if they ever have to *use* their arts.......
A school I fear is a McDojo just moved to the strip mall up the street from my house. I thought about going up and just saying "howdy", and welcoming them to the neighborhood....and talking with some of their high belts about MA.....until I saw a story on them on the local news.....and they were interviewing a 10-year-old "black belt". Yeah. Right. It *took* me 10 years to get my black. Did she start training when she was born? Really?
Eeeeeesh.
Peace--
