My feelings on sola haven't changed since Ep. 1. To me, the series has always been a relaxing, worthwhile watch (not great, but still a guilty pleasure, which is the minimum I desire from a show) despite some questionable direction and script work. Some early episodes suffered from hokey dialogue, while recent ones have been hurt by forced melodrama (characteristic of many bishoujo game stories) and awkward plot twists.
The structure
and plot devices
of AIR actually annoyed me more, but then again, I had high expectations that time (and no expectations for sola, which hasn't disappointed) given the reputation of the game.
