I've always resented Star Wars Rebels for basically becoming The Clone Wars 2.0 after the first season. The Clone Wars is okay as it's own thing, but Rebels s1 was a season-arc found family romp with an excellent villain (voiced by Jason Isaacs), and The Clone Wars was much looser tapestry of less-connected stories and I much preferred the Rebels arc format. Also, the introduction of TCW characters in Rebels really made the found family elements (and the characters I actually cared about) take a back seat.

I agree with you about The Three Musketeers. I actually refused to watch Capaldi's Doctor Who run because of it.
