I agree completely. I'm at episode 27 of Macross 7 (second run), even M7 feels like Macross, in one way or another. Delta don't, and I'm not talking about the Sailor Moon transformation, I'm talking about the dancing with Valkyries, the VF-31 entrances like if they were in a concert in stupid formations, Valks without gunpods, etc, etc, etc.
Let's do an exercise, see the first episode of Macross Plus and then see the episode of Delta, a totally different anime. I know, M + is an anime of the 90's, but Sailor Moon too. The new Valkyries (VF-31) is nice as a fighter, but as Battroid is truly ugly, skinny and without gunpod, seriously ???
