There Will Be Brawl is a web series that creates--and then exposes--the seedy underbelly of well-known Nintendo characters with exceptional dedication and insane unpredictability. It's the entire internet in ten minutes. Minus the furries.
For a series that's only ten episodes long, There Will Be Brawl is almost audacious to wait until the third episode to throw our protagonist (Luigi) into the central conflict. I'm assuming that one of the lesser reasons for putting that off is because that the acting doesn't spike up in quality to match the intensity of the characters. I hope that passion is a commodity that the creators sprinkled lightly over the series, because it just doesn't work and probably won't come to in the next seven episodes.
The benefit of using well-known characters in your work is saving a lot of establishment, but when you're putting them into such a different setting, you need to backpedal just a bit to introduce them in that setting. I'm betting that TWBB is giving us this tour not just because it's rooted firmly in giving fans a series of cameos, but because it wants us to see all the working parts before it fires up the machinery.
