Squid Girl was my childhood anime, so I'll try not to be biased about my review. From what I remember, the story itself was good. The plot was interesting, a squid girl who leaves the ocean because it's polluted? Pretty original, if you ask me. The art is relatively good, and the voice actors were pretty good (even for the dubbed version)
Each of the characters were very special in their own way, but of course Squid-Girl stood out the most, with her peppy and cute personality. Overall, the show was enjoyable and very worth the while. I'd recommend this anime to anyone that enjoys comedy and slice of life.
