First, Bokura ga Ita is drama. Drama, drama, drama. If you don't want to watch a couple go over countless drama scenarios over and over and over, then don't bother with this show.
Second, and this might be a slight spoiler, but if you like one of the male leads more than the other, this will make or break the series for you. The male lead that I liked a lot didn't win out in the end, so naturally, I'm a little bitter (okay, more than a little).
Third, don't expect real life situations or problems. I don't believe Nanami or Yano handled a lot of their situations like a normal couple would. I'm definitely no expert on relationships, but sometimes you know how things would have happen. It's TV folks, expect some "Ooooookay" scenes.
And as for my last point. The series was good enough to watch, but not good enough to warrant a "go see it now" from me. As I said, I was dissatisfied with the Anime ending, so I will most likely pick up the manga to see where it leads. Judging by my desire to read the manga after watching of the Anime, I should think that says it did well enough to see. á
