Pokémon Generations is a collection of short vignettes from the stories of the Pokémon games. Each episode is a few minutes long, they give no background to what's happening, and they tend to not resolve whatever little stories they're presenting.

If you've played the games, you'll recognize what the episodes are about, but you'll also have already experienced them in a way that makes more sense.

If you haven't played most of the Pokémon games, this series won't deliver anything intelligible or worthwhile because it relies on you understanding the context and significance of the scenes without providing them on its own.

The content of the episodes is too specific and contextless to act as a recap or introduction, and the series doesn't provide further depth to the games' world or characters, rather it just spoils specific moments in their stories, so I fail to see the point in this series unless you're desperate to see random scenes of the games in animated format.
