Yeah, it looks pretty bad from that list. It may not be quite as bad in practice - some of them may have their name attached because, for instance, they co-own a production company where only person is involved but all three co-owners get their names on the credits. And some of them may be involved on the technical side, some for the story side, some just for financing, etc.
But even so, that looks like far too many names to have any kind of coherent vision.
About 20 yeses ago - pre-smartphones - my sister lost a phone to water damage. It was in a backpack pocket during a camping/hiking trip and the backpack got rained on a lot. Everyone else's phone was fine because they were kept either in waterproof backpack compartments or in trouser/waterproof coat pockets.
Around the same time, I also had a friend whose phone was broken when we were rafting and the raft capsized. The rest of us on the raft had left our phones at home because _why would you risk bringing a mobile phone on a homemade raft?!_
Those are the only two instances I know of personally where someone's phone has been destroyed by water damage and it hasn't just been an "oops I dropped it in the toilet" situation (I'm still not sure how people manage that). And even the second example was still due to stupidity, I think - there's a reason the rest of us didn't rake our phones on the raft. My sister's phone being damaged in the backpack is the only one that didn't feel preventable, and where a water resistance phone would genuinely have been a good thing.
