I have to say that I went into the theatre with low expectations, given some of the newspaper reviews of Green Lantern that I had read, panning the movie. I'm not going to spoil the film for the folks reading this sort-of review, but I thought that Ryan Reynolds made an excellent Hal Jordan/Green Lantern, and did a much better job of it than I had expected him to. I wasn't impressed with the woman they got to play Carol Ferris, and I found that some of the plotting was a bit... sloppy, I guess would be the best word to use here, but I loved most of the CGI used for the green energy stuff, and thought the CGI Guardians and Oa were pretty well done.
The film was much better than I expected, and I suspect that if the film does well, there will be a sequel. However, I just wish they had made an Alan Scott film, rather than a Hal Jordan film. Ah, well... *sigh*
