Last season, I started keeping track of the shows I watched and the shows I dropped. Current rankings of shows I've abandoned so far this season follow, with the last episode I watched in parentheses:
One Outs (14) > Sora wo Kakeru Shoujo (2) > Ride Back (4) > Kurokami The Animation (3) > Maria+Holic (2) > White Album (1) | Worse than Cosprayers: Akikan! (3) > Hetalia Axis Powers (3)
I dropped One Outs after episode 14 because it stopped being about steely-eyed gambling and started being about people overreacting to unremarkable events and commonplace baseball strategies. To pick up the slack, I started watching Major instead which turned out to be an excellent show about baseball and sometimes a good show about gambling, too. One Outs is still pretty entertaining, but you may have the same reaction I did depending on how much you know about baseball.
I dropped Sora wo Kakeru Shoujo after episode two, but I'm willing to start it back up if it turns out to have a My-HiME mid-point switch or if something otherwise extravagant happens. I'm still waiting.
I wanted to like Ride Back. I like ballet. I like motorcycles. And I thought I'd like ballerinas racing around on motorcycles, but Ride Back is just too stupid for a show that takes itself this seriously. It would be fine if it were more over the top or Gundamesque in its science/mecha balance, but because it tries to be mature or otherwise respectable, I can't stomach it anymore. I let it go when the narrator casually mentioned a band of terrorists took over the entire world, but the cop-out conclusion to the race in episode two soured the racing aspects for me and the positively ridiculous episode four aspects (e.g., the rescue attempt, the escape attempt, the being mistaken for terrorists, the shockingly poor marksmanship of the anti-terrorist terrorists—basically the entire episode, really) turned me away completely. I'm okay with people jumping through plate glass without getting cut. It's television. But I'm not okay with pandering when it is dishonest.
I thought the doppelganger stuff in Kurokami: The Animation was pretty interesting, and some of the fights looked good. I was also intrigued by the show's apparent willingness to kill off characters unexpectedly. However, all the characters appear to be idiots and/or useless. You could trade the lead guy for a sack of expired luncheon meat and come out ahead in the deal.
Maria+Holic just isn't very good. Maybe that doesn't matter if you have a thing for transvestites and lesbians, but I found it dull.
White Album has a very boring first episode (this coming from a guy who has re-watched the first episode of To Heart too many times to remember, mind you), and none of the characters seemed to have any charisma. I was ready to punch Male Protagonist in the face when bamboozled by his confusion between live television and pre-taped broadcasts for the second time in 20 minutes. Choke yourself, guy.
Akikan! is terrible, but I probably would have continued watching it as a goof were it not for that odious Grape character. See, this kind of pandering is okay because it's honest. But Grape's voice just sounds so bad.
Hetalia Axis Powers is offensive, but not for the reasons those Koreans sending death threats give. It is offensive because it fails so hard at being funny. When a five-minute show feels four-minutes too long, you've got problems. And how.
