I thought it was alright too. I didn't think Hal Jordan was portrayed correctly. Less cockiness, and more doubtful of himself (then again I'm like that!)
Regardless, the movie seems to have jumpstarted Reynolds' acting career, and his personal life with him meeting his wife on-set [of the Green Lantern film]
And I love all the references and recurring gags to Reynolds' past as the Green Lantern. They're hilarious!
