I prefer Forward Until Dawn...
Just reading the threads, Forward Until Dawn seems to be the least favorite among the two. But I disagree, possibly because I watched FUD as a single movie on Amazon Prime. But regardless, in terms of setting up the game (Halo 4) it did so much more than this did. In terms of getting my interest peaked for Halo 5 this made me feel the opposite. Granted I'll probably eventually buy it but not when it first comes out. FUD at least can stand on its own as a movie for someone that has never played a Halo game but this, I don't know...
I stick my neck out for nobody- Rick Blaine, Casablanca
