One thing I really loved about this anime was the art and animation: it was lovely and relaxing. None o the characters seem poorly drawn or generic, and you'll probably like them in the end.
Music is really cute and always goes according to the situation. The ending song is also one of my favorites.
As for the characters, I really enjoyed watching everyone of them. Oota is probably my favorite characters, since he acts very mature and is always taking care of Tanaka. Most of the characters are likeable and their personalities shine a lot. They don't seem to take most of the things seriously and that's pretty good in my opinion.
I didn't really enjoy some of the last episodes of this series, since they included pool episodes, another fireworks episodes and a whole drama about Tanaka having a girlfriend. Most of this things feel very cliché and I would rather watch more situations.
But if you are looking for a great slice of life anime with loving characters, Tanaka-kun wa itsumo kedaruge is for you.
