Sonic Forces is above all else a case of wasted potential, the OC stuff is great conceptually and fun to play, Boost Sonic has it's moments of having some great freeform level design, Classic Sonic shouldn't be in this game he feels worse than any other game, but ultimately it all comes together in a meh package. Your OC doesn't even go super saiyan and send Infinite into the shadow realm so how could it ever live up to it's potential. I hope they return to some of these concepts in a later game without ruining them in an effort to fix the parts that weren't broken just undercooked.
