Okay, I'll try and rein myself in, but boy there are a few in each category
Like:
Jara Hamee: I loved that mofo. Toby's cool, but I just loved Jara
The Drode: You know, he only shows up in 4 books, but that guy was a laugh. A psycho, but I always enjoyed it when he had face time. Maybe because he was always getting foiled.
Erek: while I agree that the chee kinda sucked for not doing what they could have, on the personal level, I like Erek. The one liners about how so many important things are, well, his doing, I liked.
Dislike:
Aldrea: seriously, she sucked. A lot.
Visser One: I didn't like Edriss, I didn't like Visser, and while the plot device to ensnare Marco was good, I didn't like the character. Found her annoying, hardly superior to V3, and saw no reason she should be top Visser.
Ellimist: I did like him for a while, but with MM4 and TEC I just said *** it, this dude is horrible, manipulative demi-god/fate thing. Hate
Taylor: Do I need to explain
Ambivalent: I swing back and forth on how I feel on these guys
Chapman: #2, great set up, TAC, great history, rest of series toadie, and it sucked.
Tom: The brother and the Yeerk(s): Throughout the introductory arc it felt like he was being built to play a big part, but then he falls off till end when, bam, massivest part of all.
V3/Alloran: sometimes I like how blunt V3 is, sometimes the near slapstick sickens me. Alloran same thing, in the chronicles he just is already so out there, then in 8 it's like, wait there's more to it, but then we don't hear back from him till the end. Obvious reasons, but I sway on them sometimes.
