I find these people way more annoying. It's obnoxious how they pat each other on the back and whip into a frenzy if you even try to bring up anything negative about a game they haven't even played yet.
35s+ load times without anything to look at is a legitimate concern, especially when you plan to die a lot. Games like Super Meat Boy and Hotline Miami would be unplayable if they had to load at all on any death. Obviously no load is unrealistic for a game like this, but this is too far on the other end of the spectrum.
A "legitimate concern"? Please.
A legitimate concern would be if there were claims of it setting your PS4 on fire.
It's a little boring/underwhelming at worst.
Also average single play loop in SMB and HM can range roughly between 2-60 seconds.
I'd wager average single loop in BB will be anywhere from 2-60 minutes.
A 35 second load (if that) isn't going to kill you. Use the time to take a sip of tea/beer, give your partner a hug, or consider about how you could do better next time.
