At the movies, that is. i09 takes a look at Why Iron Man Succeeded Where Green Lantern Failed. The basic argument is that the GL movie just tried too hard to cram in everything from the GL mythos – all the back story, several villains, the whole corps, etc. – where in fact less would have been more. And I completely agree.
“The lesson of Green Lantern is, pandering to vocal fans of a property almost never pays off.”
I didn’t hate the movie, I found it to be entertaining, at least. But it certainly wasn’t cohesive, and wasn’t as strong a narrative as Iron man.
