For me, I think Infinite Stratos isn't nearly as bad as people make it out to be. It's not good, and I have my issues with it, but I've seen worse
I get what you're saying, but I'm not always fully dedicating time to a show. I've watched plenty of mid shows while doing other things: cleaning, playing games, working, sending emails, etc. Don't really even want to watch anything that good when I'm doing those things. Else I'll be too distracted.
