Strange Visitor To Hazzard is hands down my least favorite episode. For crying out loud, a space alien in Hazzard. If this isn't a major jump over the shark I don't know what is.
As RogerDuke said above, "As bad as it was it's still better that 99% of the shows on TV in 2017".
I've never seen Moonruners but plan to soon. That clip with Uncle Jesse Hagg looks like it's right out of the Georgia episodes.
