I haven't seen it in awhile (5 months actually), but I did enjoy it enough to give it a 9. I'd be lying if I said I remembered some exciting/funny scenes. However, judging an anime by one episode isn't good. I didn't like the first couple episodes of Beyond the Boundary that much, but I kept watching and actually ended up loving the anime. Same thing goes for Steins; Gate. That anime actually took some time to pick up from what I vaguely remember. It's always good to try a at least like 3 episodes for animes with 13. Not saying you'll like the rest of Chuunibyou, but you never know.
