Aishiteruze Baby encapsulates something what I would call a pastel coloured melancholy. It is a gentle drama that has soft, sad, happy moments blending into a sentimental yet absolutely delightful mixture. The only criticism from me is that the ending of this anime is rather open-ended -- I wish the whole anime was longer in order properly tell the whole story. It felt like it ended too soon.
Story is not only heartfelt, but also nicely told and has a satisfying pace.
Art perhaps does not not suggest the highest budget, but it is easy on the eyes and majority of the characters are, imo, cute, beautiful and have attributes which make them plausible and unique.
Sound is nothing exceptional but both intro and outro really grew on me and everything else fits in nicely.
Most characters are really quite memorable and I could not help but smile and cry together with them. I loved the voice acting as well. Kokoro in particular has a very unique and beautiful voice that fit the character perfectly.
It may be simplistic and lacking in some departments but it is one my favourite animes due the the credibility of the emotion it coveys.
