Not really the vibe of the average TV season which is the main content, the movie is kinda neat if you know the references and confusing if you don't.
I think just trying one of the year 2000 and up TV shows is the best since that'll be a more accurate example if you'll like the franchise or not (but still, there's plenty of variation even between seasons, they all aim for different vibes and narratives, so keep trying).
You can download pretty much everything from Nyaa.
