Well, the only movie I've dragged my old dead ass into a theater to see this year has been The Fantastic Four. It was my favorite comic book as a kid (I got on board with Issue #5...that's how ancient I am) and I was determined to see this. I was pleasantly surprised, especially after reading the savage reviews, at how well they did it. It's not as riveting a story as Spider Man, but it does a creditable job of updating the original. Special effects, of course, are overwhelming.
The biggest changes FF fans will notice involve the characters of Reed Richards and Victor von Doom. In the original story, Doom was not involved in the space flight which led to the heroes' transformation. He showed up months later (in the aforementioned Issue#5, as a matter of fact) as a former university classmate of Reed's who had mixed forbidden science with occult arts and had an experiment literally blow up in his face. Disfigured, expelled and embittered he went off on an unholy pilgrimage and resurfaced as the mad leader of an obscure European kingdom, a sort of cross between Dr. Frankenstein and the Phantom of the Opera. In the film, he's a Trump-like billionaire who finances the space flight and is bombarded by the cosmic rays along with the heroes. Quite a departure, but I can live with it.
More disturbing to me was the emasculation of Reed, although I think I understand why they did it. In the comics, Reed is brilliant and virtuous, but also arrogant and overbearing (imagine Sherlock Holmes in a lab coat). In the film, he is still a genius, but shy and unwordly...an arch geek, in other words. I suspect the writers realized that, since the times we live in demanded Sue be made more assertive and competent, that the quartet couldn't be four type A personalities. Ben is bull-headed and pugnacious, Johnny is a hothead, literally and figuratively. Somebody had to be the Noble Innocent...the Pogo, the Charlie Brown...to provide dramatic balance.
All things considered, I enjoyed the movie and expect the sequel, if it merits one, will be even better now that the origin story is out of the way.
