I just watched this, and Memories Off 2nd again. While 3.5 was alright, it's definatly lacking something that 2nd had. Most likely the character development, since 2nd had 3 episodes rather than 2.
But it was still interesting, and i noticed a few familiar voice actors
Not as good as 2nd, but one i'll keep in my collection and one ill keep getting since there's a few more in the series.
