I'm sure Kings Island isn't going to disappoint seeing they're replacing pavers as well. I'm glad they're focused on keeping the park spruced up lately!
Considering what used to be over there I think it's a great step up! Sure there are things that can be improved upon (as most thing can) but I really enjoyed it.
It looks like Freak Street has been replaced by "Coney Maul" (which I believe they've done before) with a new circus theme but Backwoods Bayou has not returned to the website. All these budget cuts really concern me.

I've heard "Hands To Myself" by Selena Gomez, "Make Me Like You" by Gwen Stefani, and "Unconditionally" by Katy Perry multiple times while at the park.
I'd say it's possible to get through the park without getting scared. Just be wary of what you're near and know your route. Avoid the scare-zones at all costs (they are labeled on the map). Also if you don't necessarily look scared it's less likely they will come your way.
