>>22110215I would classify it under "so bad, it's good," which made it fun to watch while it was airing. However, I'm not sure if I'd recommend a solo watch as the humor comes from it taking itself somewhat seriously despite the ridiculous feats some of the characters pull off. The characters are likeable, though, and the action isn't bad.
Same deal with vid-related. Fun to watch with friends because of how terrible it was, but not quite funny enough for a solo watch.
If you're just interested in cute girls doing spy stuff, Princess Principal is vastly superior to Spy Classroom.
