mad max - the 1st, the cheapest, and the best. probably the simplest story, yet has the most context and is the most effective at conveying that context. also, the best action by a mile.
the road warrior - getting a bit muddled for the protagonist, but still pretty good. the humungus is an excellent bad guy and cements the seriousness of the situation - either we make it to paradise 2000 miles away, or we get horribly raped and terribly murdered by the high-octane, toad-induced nightmare s&m gang. bonus: the good guys wear white and beige, the bad guys look like wrestlemania held on fire island.
beyond thunderdome - the weakest of the 3, but probably would be better if it stood on its own. the lack of a clear antagonist really hurts. so does the general over-the-top-ness, which is really saying something given the context. the movie climaxes way too early and for no apparent reason with the thunderdome 180 degree turn of events, then takes on this goonies/ewok village kind of vibe. the big car chase at the end feels really forced, lacking the passion of the 1st 2 movies. and wtf is with the pilot? the same actor is playing a different pilot from the 2nd movie, and the fact there's a flyer to provide a deus ex machina beginning and end to the story is totally a crutch after the 2nd film.
