The sad thing is that a Voyager movie with or without all the main characters would end up being the same dystopic mess as Picard has become.
It's the 2020's my friends. The era when all movies and series are bound to be dystopic, boring and with no hope.
As for "Picard" I must admit that Seven is one of the few characters there which I really like!
No, I'm not kidding, I haven't gone mad and no one has hijacked my account!
Back in the days of Voyager, Seven really annoyed the s**t out of me because she replaced Kes and more and less took over the show.
In Picard she's actually brilliant! One of few spots of light in that dystopic mess.
