I'm also a big fan of the first game. It's literally the same game but with a huge graphic upgrade. You will not be surprised by the gameplay loop.
But the big plus is the ambiance. I feel like I'm in an action movie (the fog, the effects, the music) and with friends it's awesome to share that feeling.
I don't have experienced any crashes so far on PS5. But we had long queues at the release. It's far better now (1-2 minutes yesterday). However the quickplay is still broken for me (tried yesterday). So if you don't have a group of friends to play with, it's gonna be rough without matchmaking.
Same thing for me ! I'm currently watching the season 2 of Critical Role on YouTube. It's not a TV show but it's high quality show for sure. It's a standalone campaign of Dungeon & Dragon. It's so good and there are so many hours of content !
