It’s good! I’m going to say that right off the bat: one episode in, I can tell this is a good show. It made me laugh! That’s hard to do!
At the same time… something is missing, something I can’t quite place, a certain je ne sais quoi that certain other shows–Friendship Is Magic, Steven Universe, Phineas and Ferb–have that Gravity Falls doesn’t. I don’t know quite know how to express it, I just know that, as it stands now, Gravity Falls is a show I will enjoy, not fall in love with. (Emphasis on the as it stands, though–Adventure Time lacked that something when it started, but was starting to grow it around Season 5 when I drifted away from watching.)
Anyway, you know the drill, those of you who pledged $5/mo or more can see my vlog of the first episode on the Patreon, everyone else has to wait a few weeks for me to release it publicly on YouTube.
