Not terribly faithful to the story of the comic, but I can understand Disney not wanting to make references to a character they don't own. (The whole "Doc Savage as inventor of the rocket-pack"...)
And "Jenny" couldn't hold a candle to "Betty".
I'd love to see a good pulp action film, but the only way we'll see more Rocketeer is if they do a "re-quel" of the first film. *Sigh*
They remade "Fright Night". They're remaking "Red Dawn". I hear "Poltergeist" is up for the treatment, too. Will they leave any of my high school movies alone? I think not, sadly. "Raiders of the Lost Ark" is probably safe, but "Crystal Skulls" felt enough like a crappy re-make to put a nail in the franchise...
Grump, grump, grump...
