Normally I choose an anime to review based on personal interest. There are exceptions, where if the anime is too popular or highly requested I’ll consider reviewing it, but I only review things if I really want to. This way my scripts and videos will be more interesting, because you can tell I’m engaged in what I’m saying. That’s why I reviewed Inari Konkon Koi Iroha, because I really liked the series and wanted to share it with people.
Now this could apply to my negative opinions as well. That’s why I did 42TWW Eiken, because I really wanted to talk about the show and tear it to pieces. It just depends on how passionate I am about my dislike or love of a show for me to decide to make a video on it.
