This episode basically recaps season 1. As, IMO, it targets people who hasn't seen season 1, I think it does a pretty good job at telling the main events. The best soundtracks are here, the main characters are presented. However, there was few new animation (I guess it was even none). For people who have already seen season 1, it is a great reminder, and surely a quick one, while still being respectful of the best scenes from season 1. To conclude on all this : I think it is a pretty good episode to get yourself in the mood before watcing season 2. However, as it requiredonly editing to prepare this episode, I'll only rate 8, which is my overall feeling about My hero academia season 1, minus 1 point.
