Not much to say here that wouldn't be a repeat of my review of season 1. However, season 2 is substantially better than season 1 in terms of comedy and even character writing in certain cases. Although most of the main cast is still as shallow and one-dimensional as ever, the characters are slightly more distinguished than in season 1. Furthermore, the characters I previously found annoying no longer bother me as much and the humor is far more effective now.
Overall, if you didn't like season 1, I recommend skipping through it and watching season 2 instead if you're willing to give it another shot. It's certainly an improvement and far more entertaining. However, I still wouldn't confidently recommend this season/series to anybody unless they specifically want to give Komi Can't Communicate a shot; there are better slice of life animes.
