Basically, it was ok. Ryan Reynolds was dead on in his portrayal of Hal Jordan. The movie moved slow in some scenes. For those of us who are die hard fans, there was a lot of "misnomers" in the movie. For instance, Abin Sur crashed in the desert and sent the ring out to find someone worthy. In the movie, he crashed in a swamp. WRONG! Next, green lanterns always have a green shield around them when they are in green lantern mode. Not in this one. Hal Jordan was hit with lab equipment that shouldn't have touched him at all. His eyes are supposed to ALWAYS be green b/c the power of "will" (which is green) is flowing through his body. Also, and this one was BIG! He didn't recharge his ring every 24 hours. The ring must be recharged every 24 hours or it's worthless. He only said the oath twice in the movie...and once he wasn't even charging the ring but fighting! WTF!
So, in summary, wait until it hits the $1 theater!
Black Green Lantern aka BGL
P.S.
If you don't keep up with the series, there are now black lanterns instead of just green and yellow!
P.P.S.
If you don't know the oath, shame on you!
