Just to clarify, I only watched the anime, so this review is written with regards to the current episodes alone (5 ep up to now) without any insights from the original novel.
Imouto sae Ireba Ii, an anime about a novelist and his friends, started off like any other daily-life animes. Compared to the others, one may think that the story is lacking in depth and in plot, having some weird characters and a plain MC. Nevertheless, there are some heartwarming moments inside each episode that kept me on my toes, while the story itself is very relatable, describing the daily life of a novelist and his struggles while depicting his social circle.
Character-wise, all of the characters have a personality of their own. The MC is a sistercon; his brother/sister that's perfect in all senses; different female characters that interact differently according to their personalities with the MC; the competition in life; all of them is helping to shape the MC into what he is, and while many of the characters might seem plain in the beginning, as the story goes on, we are guided into understanding each of the characters, and why they are important in their own aspects.
The music is pretty good, so far I am very enjoying the OP, and funny musics usually accompany funny moments.
The art is our usual art type, nothing fancy, nothing 3D, but this plain art-style fits perfectly with the type of story we are looking at.
TL;DR I am enjoying this anime as it takes up a different approche than most of the other daily-life styled animes, the story might be bland, but more details are given by each epsiode. Most of the characters are relatable and fun, the art and sound are fine and overall enjoyable. I encourage everybody to give this a try. :)
