Characters:
Hal Jordan - I'd like to see more of Hal's "tough guy" side, showing how fearless he really is. I'd also like to see how family is important to him, especially the father, and how he are his relations with his mother (Who's alive), his brothers, his nephew, etc... And I'd like if some of his more slap-stick quips we're replaced by Hal's classical sarcastic one-liners. More "Insurance is not gonna pay for this" and less "Oh, man! That's such a waste" upon seeing his trashed car.
Carol Ferris - Carol is one of the most remarkable femele characters of the DC history, and I'd like to see more of that. Her storyline is pretty much her troubled relationship with Hal and her trying to sell the Sabre jets. The plot we're she's secretly running Ferris Aircraft upon her father's coma would fit perfectly in this, and would add more to her as character.
Tom Kalmuka - Tom is written as a over-the-top mid-20s Nerd. It's not that big of a deviation from the comics, but it can get toned down (No calling Hal in the middle of the night to say he beat Halo 3, No sadness because his videogame aliens seem like rip-offs know he has seen new ones, and etc.). He should be funny, but more responsible, as he is the Comics. I'd also like to have him as a mechanic instead of a computer programmer, but that's not that big of a deal.
Hector Hammond - Hector is a great character, but he seems kinda throwed in the Script to have an Earth-based villain. He's kinda unconsistent (One hour, he loves having powers, the next one, he says they've ruinned his life). He has great creepy/fun moments (His exchange with the congressman in the party is funny.
), but his storyline is kinda forced (He basicly bullies everyone arround him and seeks for his father's aproval). The mind-reading is good, but kinda conventional (He only decides to read peoples minds when they're thinking bad things about he). His connection with Legion is good, but I tough how it was worked was kinda dumb ("OK, Mr. Hammond, we found an dead alien, and we couldn't find any other legists, despite that we're a governmental organ, so, we're going to pick you because your father's a Senator, even tough you're just an FBI legist and kind of a prick..."). I think they should focus more on the "super-bully" aspect of him hurting people only because, well, it's fun, and less in the Father aspect. I'd also like to establish a better parallel between him and Hal than the Father angle (They could focus on the fact they're both avarage guys who, in the blink of an eye, are blessed with extraordinary powers, and how their different creations unfluence in their ways of using it, or the fact they're the encapsulation of the Willpower (Green) VS. Fear (Yellow) battle).
Helen Jordan - They kept Hal's mother alive in the Script, but didn't used far more than just a quick discussion and a slap. She being alive adds a whole more of dramatical matter to be used, and they misssed this good chance.
Jack Jordan - I'd like to see more of him, but since the movie is alredy pretty overcrowded, I understant why's he's a almost-cameo.
Jim Jordan - He's more featured in the Script than Jack, but they kinda switched their personalities. Jim is older than Hal, and it's not as "by-the-book" as the comics. He reminds me of
Two and a Half Men's Alan, actually.
Nathan Jordan - Hal's nephew. His name is Howard is the comics, but I think they changed to make him "cooler". He's not bad (Great interaction between him and Hal), but he get's kinda annoying when he becomes a GL fanboy.
Carl Ferris - I liked Carl's portrayal. Wouldn't change anything.
Senator Robert Hammond - Hector's father. Hector desperatily searches for his approval, but he's too much of a dissapointment for Robert. He's essencially a good supporting character, but his final line
...
Jenna - Hot yoga instructor. I like.
t:
Mothef***ing huge boyfriend - Funny. I'd laugh if he's credited like that in the movie.
Vanessa - Hector's assistent. OK character.
John Broome - Hector's FBI boss. It's a classic "tough guy" who becomes Hector's human puppet because of the hard time he gave him before he gained powers. Good characters, but his final line...
), but I didn't liked how they put him in the Manhunter's AND Parallax place (Which is unnecessary, when whe get a Parallax nod lather on). The Tchkk-Tchkk storyline was pretty good. But seeing how it wraps everything together really nicely, I'm not against it. He's kinda like the Pirates of the Carribean Kraken. I like it.
