Most disappointing game in the genre?

So I'm relatively new to Metroidvanias, I've only played Hollow Knight, both Ori games, Guacamelee, Grime, and I'm currently playing Death's Gambit right now. I've loved them all, but just for kicks I was just wondering what the most disappointing MV you've ever played is and why.

Like I said, I've loved all of the MVs I've played so far, but if I do have to say that one in particular let me down a little. Guacamelee was a sick game with some of the funnest combat I've ever experienced, but I just can't think about anything remotely memorable or particularly interesting about it. In fact, I left it out of the list because I totally forgot about it and then edited it in later(and I'm probably getting downvoted for that lol)
