Agreed, I can only watch a few of them now, and only through excessive use of the DVR fast forward button. It turns out that on average from a 30 minute show, there is only about 6 minutes of actual build footage. Pathetic.
Extreme 4x4, whether you like offroad vehicles or not, has the most fabrication, followed by Muscle Car and Trucks. The reality shows that used to be OK are all soap opera trash now. Anything with Chris Jacobs, Chip Foose, Ryan Friedlinghausen, etc. is impossible to watch. I bet that 95% of those cars fall apart within 6 months too. I guess credit is due to them for making big $$ off of an otherwise tough business, but damn.
Even the DIY home repair/landscaping shows have all turned drama. I don't know how Hollywood turns bathroom renovation into Real Housewives of New Jersey, but they somehow do.
