Scream Queens : They should've paired up Emma Roberts with Taylor Lautner instead.

Roberts and Stamos had no chemistry whatsoever.

I think you missed the point. The fact that Stamos and Roberts had no chemistry was kind of the point. Their relationship was completely superficial and it was even highlighted in the finale.

I would not have liked her with Lautner. He worked so well with Billie plus they even make a cute couple in real life.
