Not so much mad as disappointed....

It seems like a cop out so that the Managaka can avoid having to pick a particular fan's ship...ie. AkanexAqua, KanaxAqua, or RubyxAqua.... Which was a big point of interest to many fans.

It also leave the theme feeling a bit hollow as Aqua says it's not about revenge but so sorta seems like it is....and as mentioned, so plot points and character development seem short changed in the end.

Finally, I'll point out that one of the early chapters has an interview with the director after the movie release where he refers to both twins, so that time line seems a bit retcon'd.
