I feel much the same way.
I agree with these points. The characterisation is so grating, so clichéd and dull. Hal is too annoying for me, I can't root for him. I'll keep watching though because it's Bruce Timm, but it's very disappointing so far.
Hal Jordan-The ubermensch who can do anything. Even though the drill sargent taught him everything he knows he's the better fighter and more skilled at using the ring. Ok Hal Jordan, best at everything, and the male version of Mary Sue.
Razor-Obviously he's on the path of falling in love with Aiya and will redeem himself.
Aiya-The robot who learns to love, and also the one who fills in whenever we need exposition.
Kilowog-The bigmouth who always gets shown up. Always. He just got his arse kicked by a mook this episode. A big mook, but a mook all the same. He never succeeds at anything he does except beating up the lowliest of robots.
These episodes lately are still better than what were being shown earlier. Like you redred, I'm sticking by it because of Bruce Timm.
