Terrific fun, very quotable, but far from great. It's not as bad as they want you to believe...
Obviously, it's a Hollywood-endorsed sequel. The original two are wild Ozploitation films, whereas this entry in the series feels like an attempt at being a set design/costume & make-up Oscar-beg.
'Mad Max Beyond Thunderdome' is fun until Mel Gibson's Max receives the "gulag", after that, the film is not fun - majority of the film, unfortunately.
