There's many ways to look at it, unpredictability is welcome at the current era of predictability (Pog&MVP), and if the possible winners of this race were Wout & MVP, then this particular randomness/luck was more than deserved for the former.
But randomness of punctures at PR aren't desirable in a vacuum, IMO. The main problem is the lack of rider control, sure probably over multiple events better ability on the cobbles will reward you with less punctures, but for this event, I seriously doubt there was any particular mistake from MVP/Pog/Wout that caused their punctures. When you add to this the fact that depending where it happens, as seen in this race, the cost can vary between 15 seconds to 2+ minutes, yeah, I'm not a fan in general.
