The Witness was repetitive? Every puzzle set had a lesson, and every set of sets had a gag / out of the box puzzle at the end where something was fundamentally different (a crack or flicker, or an interaction with the environment, or a reference back to something else on the island.)

What I suppose was repetitive though — and where you might be coming from — is the formula itself. The entire island was the same episode format, even if the plot was different each time. Like Knight Rider — formulaic, but I loved the formula!
