BTW, The Magicians TV series might be the best thing SyFy ever made. It's got so much heart, it's properly funny, it's creative, it's epic despite a shoestring budget, and the characters stay with you long after you finish.
But yeah up until that point it was great!
The Magicians overdid it though. It's not a musical episode, iirc it's like 2 seasons
Edit: just to be clear, I still watched those 2 entire seasons, because the story is genuinely that good, plus I was invested. But I really wish they hadn't gone musical, it really messed with the mood of the series.
