Roller Jam

You can tell that they know they don't have a lot to fill up each show because they are constantly stalling for time and dragging things out unnecessarily. Not much happens in an episode so it really drags for time. 40-50 minutes is too long. If they were 20 or 30 minutes max it would seem more eventful.

They should have put the contestants a gauntlet of roller skating skills to make each team perform so you can see the technical abilities of each team member, both their strengths and weaknesses. Like a mini roller skating Olympics. Skating backwards, jumping, spins, etc. Taking a note from figure skating. If they do another season they really need to pick it up the pace by building in more structured content to the challenges.
