There's a lot of stuff in the small details throughout the more episodic early eps, too.
Some retards insist on naming specific episodes "where the plot starts", but all that's gonna do is lead new watchers into skipping everything before that because hurr give me the plot durr what can I skip, and then they won't get a lot of stuff.
The reason the show feels so amazing is because one watched all the errors and the build-up and the shift from the lolsorandom harmless quirky fun to the serious shit hitting the fan while going down game of thrones meets harry potter meets madoka tier stuff. It won't feel as good plus you won't properly get what's going on if you skip a lot of stuff.
Plus if some faggot can't deal with the humor and only wants to see "serious" plot and wants to drop the show after 3 eps or whatever, let them. I do recommend watching till Mewberty or Blood Moon Ball before making up your mind - but the loud quirkyness is at the heart of the show even if it tones down later, and if that's repulsive to someone maybe Star vs. isn't the show for them. People are going like "it takes a while to get going" as if the serious shit is the true show and the loud fun only pointless filler in the beginning, but it's a core part of the show too
