When I heard the villain would be Parallax and not Sinestro I immediately thought "WTF?". I gave it the chance it deserved, but as it stood, the movie gave the audience zero interest to care about defeating Parallax. I think it's a no-brainer that the movie should have had Sinestro turn from good to bad during this movie and become the primary antagonist. I don't really understand why they thought it was a good idea to put that off for a sequel that might never get made.
I guess I'm the only one, but I thought Parallax made a plenty effective villain in this. From his ferocious attack on Abin Sur in the opening, to him ripping the skeletons out of people left and right, I don't see how he could have been any more
threatening. And him being the embodiment of fear didn't seem all that hard or abstract a concept to grasp.
Obviously Sinestro as the villain would have been pretty awesome as well, but I didn't mind waiting til the next movie to see it.
Green Lantern the movie was boring, drab, unimaginative and incoherent from beginning to end. Simple reason why it failed.
The first three I can kind of understand, but I still don't see what was so "incoherent" about GL. It was as simple and straightforward a story as you can GET. It might have got a bit rushed here and there towards the end, but it was always easy as hell to follow. There was never a point in the movie when I was wondering "Why is this happening? What is going on?"
