Keller. He was the most reasonable of the bunch, and he was awesome with a shotgun XD. I wish he could have returned for the sequels. Galloway was an asshole, but a reasonable one as he presented the voice of those on Earth who felt it would be a good idea to remove the Autobots and thus the Transformer war from their home. But as Optimus said, “What if we leave... and you’re wrong?” Mearing, ugh. She had a Gilmore Girl as her adviser (literally - http://tfwiki.net/wiki/Keiko_Agena), she had sex with Simmons, she had her femininity questioned in a manner meant to be humorous but was less than funny, and she was like “you’re not a soldier, just a messenger” to someone who served with the Autobots twice. Can’t wait for the next official they’re going to have in TF4. Maybe it’ll be OO7’s Judi Dench LOL... wait, Judi Dench in TF4 would actually be awesome.
Keller, certainly. He was the most reasonable of the three, and aided the others in fending off Frenzy and calling the airforce. Mearing was good though. Galloway can just go away.
Keller was my favorite because he was the most reasonable and he wasn't just a jerk. Galloway and Mearing could have been the same character because they basically had the same personality and goals. They each worked for the movie they were in.
Keller never really caught my attention and I like there being someone who wants to get rid of the Autobots. So out of Galloway and Mearing, I have to vote for Mearing as I could actually stand her.
Keller. I could actually tolerate him, mostly because he was reasonable and written to be likable. Galloway can go to hell. Mearing was better than Galloway though.
Mearing or Keller. (Gave my vote to Mearing) Both were reasonable, believable characters. Mearing was kind of abbrassive but had reason and was quite clearly still on the right side. She wasn't needlessly accusatory. Keller was likewise well established as a guy doing the rigth thing and not just being a jerk, but he felt kind of plain. Galloway was just dumb but it was funny when he got kicked out of the plane.
Keller without even thinking about it. I hoped the other two would be stepped on every time I saw them.
Mearing! I respect a woman in such men company She very like her work, but, because she try to similar to males, she almost don't express emotions. And her phrase about Sam as a messenger is a great wisdom. He is messenger, it's true. Autobots are heroes. Remember finale of DOTM.
