I really wanted to like this show. The main characters are fleshed-out and likable and the show doesn't fall into the harem trap where all the girls end up having a thing for the main character. The "main girl" (of sorts) is a cute denpa-character that offers a few laughs and several very cute moments.
Despite having everything one would think it takes, this show still just had episode on episode where I found myself checking how much was left. I can't really put my finger on it, but even as a person that can easily breeze through a mediocre harem I found this show lacking in ability to engage me in any way (and it tries, perhaps too hard at times).
I'd personally give this one a miss. There are plenty of other good shows in this genre around.
