In what order should I watch Pokemon TV show and movies?
There are a few different ways to do it, but there’s really no “standard” way. The most common way is just chronological order, going from the first episode of the TV series to the best, and then skipping over any episodes that don’t appear in full on DVD or online streaming. Some people prefer to watch all films before watching any episodes because it does make sense if you think all Pokemon movies have a standalone story and follow Ash’s adventure at some point in their narrative.
The other option is simply going with whichever incarnation of Pokemon you happen to like better (the games, the anime series, etc.) as they’re produced by different creators who work separately from one another without any reference material.
