It sure was entertaining to see them run on a brand new engine, gearbox and electrics on full race power (they probably have even more for qualifying) instead of the usual economy mode to reduce wear and tear. And the Interlagos track is a phenomenal race track despite the lack of overtaking opportunities.
Some race tracks just don't provide good racing and some are downright boring to watch despite being fun for the drivers. This is even more of a problem with Formula E, which usually runs on street circuits with mostly 90 degree corners.
A lot of F1 fans complain about grid penalties, but watching guys like Vettel, Hamilton, and even Ricciardo - guys with a legitimate shot at a place on the podium - make up time and set fastest laps to move up in position has been a lot of fun this season. For better or worse, the very front of the pack tends to be more quiet. If you're in front and your position is safe, you won't generally set fastest laps, you'll preserve the car.
