Better than early Bond films?
I must say, I enjoyed Danger: Diabolik more than the early Sean Connery era Bond films. This may come across as film sacrilege, understandably, to make such a statement, but I really believe Diabolik takes me to a place that Bond films don't.
For a male/action/spy/fantasy film, Diabolik has better pacing, more action, sicker bad guys, groovier sets, sexier women, cooler gadgets and a really hip anti-hero. I love Goldfinger, Thunderball, From Russia With Love, etc. but I have to say that the subplots and espionage scenarios now seem boring and dated. Every aspect of Diabolik is fun, adventurous and "exhilarating". And isn't Diabolik's lifestyle more alluring than 007's.
Not trying to disrespect the Bond film series, which made a movie like Diabolik possible. I just wish more people knew about this lost gem.
