I think Paramount really killed a lot of what Kings Island really was and CF is in for a long road to bring it back to it's glory. The overabundance of commercialism (every single new ride except SOB being themed after a movie) and the focus only on 'bigger and better' took out the family aspect. I personally think Cedar Point is a great family park for rides - they've got a good amount of little kiddie rides (more than Kings Island) and lots more flat rides. I definitely enjoyed CP's flat rides more - from the high thrills like Chaos and Witch's Wheel (PKI took out Skylab the year after I rode it the first time) to the family oriented things like the Antique cars/turnpike cars/Cadillac Cars (yes, they have THREE car rides at CP), and the spinning rides like Matterhorn, Calypso and Super Himalaya.
I'd like to see a wider variety at King's Island, because now that I've visited Cedar Point several times, I find KI lacking in flat ride variety. I still think it's a great park with great coasters (and there is no coaster in existence that even compares to The Beast, IMO) but there's only a small handful of flatrides that adults can really ride and enjoy - Monster, Shake Rattle n Roll, Scrambler and a few others. They could benefit from a lot more flat rides that are family friendly.
I do think they're an excellent park for 'growing up' to coasters. I started out on The Beastie when I was 10, being absolutely terrified of the idea of coasters but loving it once I got up the nerve. At 11, I rode the forwards Racer and Adventure Express. The summer I turned 12, I started out on Flight of Fear and never looked back.
CF has also brought back shows - I don't even remember them having shows (though I know they did have one or two) when Paramount owned it. Now I can actually name off a few of the shows, and they have live entertainment on the International Street stage again, which has been done in a while. The park overall is cleaner, security is more visible, and the staff seems much friendlier. I think they're taking giant steps towards bringing Kings Island back to it's former glory. Though we'll probably never see a return of the monorail or zoo area, I think they'll do some good things if we give them time. My biggest hope for next year is that they return some of the theming that's been left to rot - the old western town on the train route is barely even there anymore because it hasn't been touched by maintenance in so long. A return of the fog and strobes to Flight Deck would make that ride exciting again. And could someone PLEASE dust in the queue area of Flight of Fear?!
