Games that look terrible/generic shovelware but are actually amazing to play.

Bayonetta 3 was ugly by Switch standards, but it was a blast to play.

Sniper Elite 3 looks low budget and uninspired, but has amazingly satisfying tactical action.

Medal of Honor Heroes 2 seems like just another generic WW2 game on the surface, but the smooth and creative controls really elevate it.

Bayo 3 was one of my biggest disappointments this generation.  It looked like hot garbage, run poorly and wasn't as good as Bayo 2.  Still a really good game and I enjoyed it.  But lord I hope it gets a S2 port with way better graphics.  Overall, it felt like a step back.  

Since you mentioned Bayo 3, I think Astral Chain fits the bill here.  Very generic looking, at least IMO, but an absolutely amazing experience.
