Harem endings are best when the girls involved are as hot as Nagi and Sammy. You get two different character types too. Too bad the coffee they serve will taste the same.
After watching the movie, I have reaffirmed by judgment that this show is truly a masterpiece. I think I liked the short episodes more though, because the intro song does not get cut off, and each story feels complete per episode even with differing lengths.
I love the Akiko and Rikuo interactions the best though. I might be influenced by the VAs playing them though.
