If you haven’t watched Over the Garden Wall, you should give it a try and watch every episode, especially if you’re looking to get into the Halloween spirit. The whole miniseries isn’t that long - about the length of a feature film in total.
Also, my gosh, it was so miserable to put Bashir’s skinny pointy little face onto Greg’s big round chonker! But bird Garrak was worth it in the end.
The year it came out it had quite a few cosplayers. I think most people do not know it because it was a short show that didn’t need more seasons. It basically suffered from success. Its a good Halloween season show.
