No. No! Bad, poster, BAD!
Flash Gordon is an amazingly fun adventure with the best fucking soundtrack on Earth. It is amazingly quotable, it is visually dazzling, and fucking Brian Blessed is in it.
Nope. It was a garbage can set on self-destruct from frame one, and its no wonder it took an instant nose-dive when released. When filmmakers assume they're doing
"That--er thing that inspired Star Wars! We already have the rights to it! Let's do THAT ! That'll show 'em! We will out-Star Wars Star Wars!" and abuse a concept they clearly did not understand, what happened was no surprise. Then again, DeLaurentis also pulled the same crap in 1977 with
Orca, his nonsensical answer to
Jaws starring Richard Harris versus a vengeful whale, so anyone working with him should have seen that coming...
Now, sit in the corner, you can come out when you realize how wrong you are.
Now pull that needle out of your arm, because whatever you're using, its clearly altered your mind.
I think the fact that it was written by one of the Batman '66 writers tells you everything you need to know about it.
Just the opposite; one, the man you refer to is Lorenzo Semple, Jr. who was responsible for the more level-headed, early development of the
Batman series during its undeniably best season (the first), where comic action, even occasional noir influences were seen. Two, it was only after he backed away from the series (the remaining two seasons) that producer Dozier and Stanley "Never-met-a-schtick-he-didn't-like" Ralph Ross upended the original 80/20 mix (80-comic adventure, 20-a
soft tongue in cheek about
some elements) to become the stereotype that has mischaracterized the original intent of the series ever since. Regarding Semple and
Flash Gordon, from production materials I've read, he thought the character should not have been treated with any humorous elements, as the source was nothing like that at all. He has said the film should have followed the classic Alex Raymond comic strip. During production, he had some disagreements about this with DeLaurentis, but the Grand Master could not be convinced to dump many of his wrongheaded ideas and the result was the gaudy,
"this is the biggest sci-film!" dreck that met its deserved end as a bomb.
I don't think it's really fair to count movies like that as "bad", when the "badness" is half the point.
It was not a parody--being bad was not the intent of that film. This was not satire of bad films like
Amazon Women on the Moon (1987) or a genre take-off like
Scary Movie (2000), etc. This was supposed to be some great sci-fi epic stuffed with wrongheaded ideas about what heroism in sci-fi / sci-fantasy was supposed to be. DeLaurentis had the best template for that of all--the wonderful Raymond strips--but jettisoned the very things that made FG a classic creation. The rest is history.
