I get the feelings. But I'm a bit surprised you are responding this way. I mean, have you ever been on the internets before? What do you expect?
You are getting this sort of response because the idea of the show DOES appeal to people. And much of it has been enjoyed.
It also appears you've never been part of the semi-harsh world of comedy. It's hard. You get shit on. (And the folks you shit on are always going to be louder than the folks who love something.)
Just as some contestants don't get leeway for the difficulties they have and the learning process they had to face, The Challenge isn't always going to get leeway for just because you are "trying something new."
There have been MANY reality shows you could have studied and learned from. And you guys did. But some lessons didn't seem to be taken. (One reason most shows have a panel of judges that return week in a week out is so things are consistent.)
And just because you tried to address a complaint in the forums (challenges repeating themselves) and tried to do something different and then had it go poorly, don't take it personal. Learn from it, but get whiney.
Look at the criticisms you agree with and learn. Ignore the rest. You don't have to justify yourself to anyone.
