I enjoy watching several roleplay streams at the moment. They haven't eaten into my D&D playing time - I'm currently in two weekly games, which is higher than my average over the past few years. Instead, watching these and similar shows has supplanted my viewing of traditional television.
Last month I cancelled my subscription to Sky TV that I've had for somewhere going on 20 years, because I came to the realisation that I hardly watch any TV on television these days. 75% of what I watch is on YouTube or Twitch, and around 20% is on streaming TV services like Netflix. The remaining 5% of traditional TV shows, I can still view via streaming services such as iPlayer.
I'm a little behind on Critical Role right now - the shows that I watch weekly are Roll4It, which just finished an entertaining Star Trek series and has a fantastic ongoing Buffy the Vampire Slayer series, and Geekspacetv, for their Stars Without Number series.
I don't watch particularly for gaming tips (though they can be educational in that regard) or to see people who are somehow more 'professional' at playing non-competitive board-games, if such a concept even exists. I watch them to see people I like playing entertaining characters, and generally just having fun with each other.
If you go into these shows with the mindset that you're there to watch a game or a sport, they will disappoint you. If you approach them with the mindset that you're going to watch an entertaining story with strong elements of structured improvisation, then maybe you'll find something to enjoy.
