Well, I just came out of the theater after having viewed LXG. First off, I do not think it was a bad movie. While i would not recommend it as a must see movie, I certainly didn't find it to be a waste of my time. Sure, some plot points could have been developed more/better, but hey, I didn't walk in expecting Shakespeare. Though I haven't read the graphic novel on which the film is based, I have read that both the graphic novel and the movie take place in a reality alternate from both out history and our literary canons; which means that even though Stoker never wrote Mina as turning into a vampire, it's okay for LXG to take the license to do so. And so on and so forth.
Yes, it would have been nice to see Connery make his character a little more swashbuckling. But maybe that was the writing. I almost loathe watching anything with Peta Wilson, but i found here surprisingly interesting in this movie. In fact, other than Tom Sawyer's character seeming a bit incomprehensible, I think the other Leaguers were pretty interesting. But what was the deal with the bad guy, "M"? I thought his M.O. was even more pointless and less fleshed-out out than any of the flattest Bond villains I've had the displeasure of seeing. It was just a badly written character.
Just a word or two about the Mr. Hyde F/X, the CGI wizards of the Hulk could take a clue. Sure, both characters were CGI rendered, but Mr. Hyde's size carried a credible degree of mass and weight, whereas the Hulk often moved as if mass-less, making him seem too two dimensional.
All in all, I give the movie a respectable 6/10.
