Green Lantern

I bought this blind a few months ago on blu-ray. Walmart had the Extended cut for $7.50 so I thought that even if it wasn't that great, what harm have I seriously done? I have noticed its reputation is not that great and I'm not a fan of Ryan Reynolds, but it is said to have nice visual effects (the screen bleeds green). I haven't been that inspired to watch it yet because of its reputation, but I might find myself surprised just because my expectations are so low.
