I watch it, I like watching the group dynamics although in terms of business lessons it doesn't have a ton to offer, in the first few seasons were more watchable in that respect. Also I find Trump kinda fascinating to watch, despite all the things that one would normally find detracting (ego etc). I find it interesting how he embodies a role (the big NY billionaire) and plays it unashamedly and boldly, it reminds me of the world view the author of the 48 laws of power (Robert Greene) talks about.
I like watching the 'Dragon's Den'(UK tv show) and seeing how entrepreneurs pitch/fail to pitch and watch how potential investors evaluate deals.
I'd love to see other types of reality shows that follow startups & entrepreneurs.
