So far I have a few series done perfectly, but quit after becoming hopelessly stuck on one (I think it's one of the movies with Sabrina).
That first one with Sabrina was where I got stuck as well! The rental Pokemon you get stuck with on the first attempt (a Vanillite) is just terrible because her Swoobat always one-upped me and caused me to fail the requirement every single time. That was where I gave up on Pokestar Studios and never returned to it.
