That "flavor" (Billy Jack etc.) and all the biker 'sploitation movies are just awful. I'd disagree with the notion that they haven't aged well. I think the more accurrate decription is that they sucked from the start. I'm including films like Mad Max, etc. that are considered apocalyptic cult icons. Those movies are trash. Even supposed period piece blockbusters, like Bonnie and Clyde from that era of film are blech...
Most film noir movies from the mid 40's, to late 50's, hackneyed as they COULD be, are better than most 60's/early 70's "art" film, IMO.
Back to your question though:
Most James Bond films.
Guess Who's Coming to Dinner
Casino (never thought much of it in the first place)
Dr. Strangelove
The original Superman
Almost everything that Kevin Smith made.
