Not really sure what the budget has to do with anything. Just because GL may not look like the 200 million movie it is, doesn't affect my enjoyment in any way.
It didn't actually cost 200 million, but that's kind of a moot point because a lot of other films don't actually cost as much as is claimed either.
I really don't see how they could have done much differently and been as faithful to the Green Lantern comics and mythos as they were.
Well, I'm usually
one to argue in favor of ditching anything and everything that the filmmakers think doesn't work for them in the translation to a movie, so I'm in the kind of odd position of being happy that they didn't - I really love GL, just the way it is and has been - but having to accept the commercial consequences of that as the cost of taking that risk. C'est la guerre...
but I'm sure glad that they did this one they way they did it.
