I watched the entire season today, and the show is actually pretty good. It does a much better job at capturing the tone of the books, and is a much more faithful adaptation overall. I like the progression, I feel like they spent just as much time in each place as they should have. It's well cast, particularly Neil Patrick Harris as Olaf, who does a way better job at playing the character than Jim Carrey did (as much as I like Jim Carrey, his portrayal of Olaf had too much of himself in it, and was too over-the-top for my liking). It's got the perfect balance of humour and drama to match the books, and I really like Lemony Snicket's role in the show.
Overall, I'd probably give the first season a 7.5/10 or maybe an 8/10
