I think the movie format only brought out the weak points that the story of Dream arc already had, so direction is not to blame. The postproduction is fine, the character designs are nice, the music is very repetitive and you can clearly hear all the other Yasuharu Takanashi works in the soundtrack. I will never understand how this guy gets so many jobs being as repetitive as he is, but whatever. Outer Sailor Senshi introduction rules though. This is fine, but just fine, and only thanks to the quality of animation. There isn't much more that could have been squeezed out of such sourcematerial. Therefore, thanks Toei, now give us Stars (original Stars arc is a blast!) <3

MANGA SPOILER
I really wanted to see the Shitennou cameo :(
