"ruined by people that have no idea what made these series great." he says in a review for a game made by guys who worked on the first four Silent Hill games.

bro the guy that directed this directed wii play and the new super mario bros minigames, the only good parts of the game are the parts done by ito and yamaoka, the monster design and the soundtrack specifically.

The game director role is purely honorary if you did a thing called research. That’s why it’s lumped with producer in this instance- the man listed is the general franchise producer.
And Ito did not just do “the monster design”, he’s pretty much the driving force behind this entire game, since this is based around a concept he had been talking about for years. The additional scenario writer was likely there primarily to flesh out Ito’s ideas further, similar to a lot of work on Silent Hill 2 and 3 (and this is indicated by the additional scenario writer being from Higurashi’s console ports).
