^All I can say to the above posts are that YMMV. Many folks that do "other" yoga will say they dislike Bikram for one reason or another. And hey, that's fine. Nobody says you have to go. I do laugh at some of the complaints I hear from people that hated it (it was too hot - OK, if you don't like the heat, don't go back - or "they were telling me what to do" - well yeah, that's kind of the point, if you want to just do your own thing, do it at home and save the money, lol).
Captnoblivious: regarding, the crowding, that is variable from studio to studio. I've been to studios that cram 55 people into a room that should not have more than 40 in it, and I've been to studios that get 15-20 people per class. I like it being "crowded but not too crowded" but that's my preference. Again, YMMV. My "home" studio generally gets about 20 people for Saturday/Sunday morning classes and I'm never forced to "touch" my neighbor, but there are enough people in class that the room gets nice and warm.
Re: the pose sequence being "boring" - that's actually one of the things I like about Bikram, lol. I enjoy going to a class and knowing exactly what the poses will be every time. I only go to the studio once or twice a week as "active recovery" - maybe my opinion would be different if I was going to class every day.
I do kind of chuckle at your comment that it's the "Crossfit of the yoga world." FWIW, in my travels, most Bikram studios are very friendly and welcoming. I have occasionally encountered an instructor that I thought was kind of a dick or someone that would have definitely scared off beginners. Being a good yoga instructor requires an ability to assess everyone in the room and tailor your instructions and demeanor to each person as you give comments and corrections.
Facepalm_Death: just my opinion, but I have tried to do Bikram postures at home and have never felt that I could match the feeling of being in the room. It's not just about the heat, although that's definitely part of it. But also having an instructor in the room to make corrections and give cues (head back, chin up, right shoulder forward, etc) is helpful for me. I also enjoy the social aspect of being at the studio and chatting with my friends there before and after class; but I understand that some people just don't care about things like that, or have other places to get their social jollies on and don't need friends at the gym or yoga studio.
It's expensive, yes. Personal choice whether paying the money is worth it to you. I think it is for me; but, yet again, YMMV.
FWIW, Bikram Choudhury, the man, is a complete scumbag. However, I have spoken to several studio owners and they've all confirmed that Bikram receives no money from the studios once they're up and running - he only gets money for the teacher training.
