I just finished watching the third episode and I think it is better than the first two. This episode was dedicated to Loid’s childhood or background. This season has a serious tone as compared to the previous seasons. I think this will be the last season. But I am not sure as I don’t follow any anime news and community, maybe there is content for another season, but I think they should end this anime in this season only. So far I liked the third episode and I would rate it 3.5/5.
