Anime like this having ratings below 8 are why I don't trust ratings for finding anime. People don't appreciate quality that isn't pushed into the mainstream. The two main characters play off of each other so well, that i'm incapable of providing enough descriptors to explain what makes this show so enjoyable. Every episode is a fun reactive to proactive interaction. The side characters though, provide little to to show, though they aren't the focus at all. Watch even the opening the get a feel for the wackiness of these two classmates and maybe you'll understand why I love this anime
