The biggest resource for Flash Gordon is actually the comic strips, but there have been many comic books, regualr books, and even a animated series as well with ming having loose ties to hitler in it.

While the new show probably could have had far less controversy had it been called something liek rift riders or some such, they chose a "name" and even went so far as to use the old flash gordom queen music in promos for it before launch. marketing really should have known better.

Way too many people take way too many things way too seriously.
