great minds think alike! i saw this today, and was, tbh quite disappointed. I wouldn't call it exactly bad, just...average. With too many wasted oppurtunities to list them all. Needless to say, having read the first volume (indeed i bought it in graphic novel format) i can safely say if they'd have stuck more closely to the plot, it would've made for a better film. The steampunk setting was not played up enough, why was Alain Quatermain played up as being the group's leader? (in the book, all the characters are given more or less equal standing), where was the go-between Campion Bond?, why was Moriarty looking young and strong?, why was there such a gratuitous use of guns? (in the book, as you'd expect for turn-of-the-century, swords and other blades are used far more often), why did Dr. Jekyll have to drink potion to become Hyde?, why did the invisible man most of the time have a very solid-looking face? (the effect they used initially should have been used throughout), and what the hell was the amoral and more importantly American Tom Sawyer doing in the very British League? Ok that last one prob'ly needs more explaining - the characters themselves may not all be of British nationality but they are famous figures of British literature. To my knowledge, Tom Sawyer is from two books written by an American author, and anyway i seriously doubt if someone doesn't know any of the british lit. figures they're any likelier to know who tom sawyer is, so as a concession to less "well-read" (loosest possible sense) people it's pretty pointless.
No doubt sean connery wanted to be sure of being the "main" character, and whilst i can understand each of the League having to have their back-stories explained, however briefly, in order to familiarise those of us who have not even heard of them, i can't help thinking the comic's way was far better. Overall, at the end i realised the film gives the impression of having been written and/or directed by someone who has heard of the comic of The League, possible even had a flick through, and then gone and written their own story using a very similar idea. Even as an action film, it is merely ok. Fans will more likely than not be disappointed at the plot changes and concessions to a wider audience, whereas the wider audience may well be confused, or at least daunted, by the selection of characters and how they fit the story.
oh yeah, here's a blooper for ya: when jekyl changes into hyde, obviously his whole body grows. So how come his shirt and any other top clothing garment rip whilst his trousers magically grow and shrink to fit?

i personally hadn't expected much of this one, but when i actually saw it i thought it was a great work. the special effects are great and not too many but used in a great way. the story is not all that, but i personally enjoyed the movie a lot because of the way it was made.
