There are a number of movies that came out that were generally panned or poorly received. Not unusuall, but I think these were unjustly maligned. They were each based on source material that was largely foreign to the movie audience. They were each, if not great, at least good (and usually faithful) adaptations of their source.

Popeye (1980)

The Keep (1983)

The Shadow (1994)

The Phantom (1996)

The Saint (1997)

The Avengers (1998)

Flash Gordon (1980)

Dick Tracy (1990)
