I try to overlook the ranger project. Ian is clearly a general automotive expert but he's pretty new to 4x4s, so is Jesse. Their show is entertaining and I'm sure that in a few seasons they'll be past the early stages of their learning curve and it will be a lot harder to find flaws in their work.
Woodworkers went through the same thing when Norm started the New Yankee Workshop. He early stuff sucked and had obvious design flaws but his new work is actually pretty good (if you can forgive all the nails he uses).
