I like that there was more singing too. That last few bits was actually book 5 and I was SO SO SO excited because I just finished book 5 and it's my favorite book (so far). These last two eps of the show are my favorites.
Back to the ep, I think it was nice to see how much bond the orphans have in this episode. Klaus & Violet were amazing as always. Poor Charles being hypnotized too. I'm actually glad Dr. Orwell died. Her death in the book was gruesome so I somehow knew they were going to change it on the show.
I actually felt sad when Mr. Poe was saying goodbye to the orphans in the end like there's some finality to it. But he's not really good at his job so I'm also half-relieved that they are in boarding school.
