All right, guys.. I actually went in for a second viewing. My cousin - who is also a GL fan - forced me to watch it with him and his wife again. I got encouraged because my sister told me earlier that she loved the movie a lot. She said she didn't know what I was talking about when I said it was bad. It made me scratch my head, but she explain to me that maybe because I read much more storylines in the comics, I was expecting something else. So that opened my eyes a bit. This time, I went in knowing what to expect and with a more open mind.
To my surprise, it really wasn't bad. The first hour + the final battle were quite enjoyable. The problem is within the stuff in the middle - it needs better pacing. Other than that, the movie does a nice job introducing new comers to the Green Lantern lore. Think of this as an introduction course to the world of Green Lantern. Don't fo in expecting what we read later in the comics. After all, this is just an origin story. The movie didn't fly with the critics because it suffered from "Origin Story Syndrome".
Guys, I realize noe that the general public - including kids - could very well like this movie, but many will be put off by the insane amount of bad negative reviews. It is being unfairly judges IMHO. If it was released just 2 years ago, it would have been a different story. I honestly believe that if they make a sequel, it will all pay off.
I actually blame the marketing. Not because the lack of it, but because it is misleading. We got fooled. There was a strong emphasis on the different Corps aliens. Even the movie's standee features many of the aliens we don't really see in the movie. It suggests that they have major roles, but they're only in the background for few seconds! Also they revealed almost all the scenes with all the trailers and TV spots.
Here's hoping they have the balls to greenlight (heh!) a sequel.
