WOAH this was a polarizing song. I am biased as my ult is Dreamcatcher, but even I have to admit that this is a pretty stark difference from the other songs of the past.
It's been about a week, and I'll definitely say I appreciate the nu metal-ish feel that the song brings. The aggressiveness and highly confident vibe is really interesting to see! The MV itself showcases all of that.
All in all, I wouldn't say I would put this in my top 10 Dreamcatcher songs, but with how long the group has been around, I see it as an appropriate (but hopefully temporary) change in sound.
