Heavy Rain is maybe worth I look I feel for some the intense set pieces, but the writing is terrible across the board for more or less everything Quantic Dream has conjured, which is a significant deficiency when the genre is so reliant on consistent, believable character and narrative writing.
Until Dawn is what happens when an interactive screenplay is penned by writers already deeply experienced and proficient with television and film screenwriting principles. It's evident from right out the gate and never lets up, particularly in how seamlessly scenes blend together, the characters are interwoven in and developed alongside ongoing events, and the narrative is structured as a whole.
I don't think it's a perfect game, but for most part it's written to know the strengths and weaknesses of the genre, successfully transitioning cinematic principles in screenplay and directing to an interactive work. It's incredibly self aware and confident with its themes and cast. It's probably one of my most surprising gems of this gen, especially considering Quantinc Dream's awfulness was the flagbearer for this genre on Sony's platforms.
