I am not a fan of this sprint structure. I am positive the sprint race will be a train. I do think we need to be wary as if the fight at the front is exciting, we should not get ahead of ourselves and declare this a success.
Competitive seasons in F1 are a rare with periods of domination more pronounced. A sprint structure only works when all cars are equal and there is nothing to choose between them. It works for Formula 2 because the cars are very, very close. In F1 passes for the lead happen mostly in pit-stops or diagrammatic errors which are rare.
