My 2.5 year old loves watching classic Pokemon. I'll be honest, so do I. But have you tried doing that? It's fucking insane.
The first half of S1 is on Netflix
The second half is on Amazon but you need an extra subscription to watch it.
The theird season (johto) is also Amazon.
The 4th is no where but Archive.org of all places... Which is called Johto Champions, so it really feels like the end of the season but it's another 52 episodes!
You would think pokemon.com would have all this (they have a lot, and it's all free) but they don't!
Seeing S4 (is that even right?) On Archive.org is really pushing me to want to build a Plex server. Having all this content in one place would be very nice.
I do IT work by day, and I have some older 2TB platter drives from a retired camera server laying around. What's the easiest way to get my foot in the door? Do I save up some $$ for a Synology box?
There are also free ones, BUT they're a lot harder to get into, and a lot of times don't have as much content or aren't managed as well. They do exist if you're patient though, I managed to get into a pretty good one a while back.
