Wonka is a great game, the flow and depth are first-class, Lawlor at his best. It's a toss-up between Wonka and Dialed In, both are great games that offer different things, some weeks I just turn on Wonka, then its Dialed In. So hard to say which is better.
I'm not really a 'theme' guy, as I dislike Wizard of Oz but love the JJP game, Dialed In meh its an OK theme (I'm not like Pinsiders that moaned about it based around a phone, so what) but its a great game, Wonka also not really my 'must have theme' but equally a great game.
Guns and Roses as a band I can take them or leave them, but the game looks freaking awesome.
As for it being loads of multiballs? So what its in a home environment so its meant to be fun.

@Colywobbles said, Hobbit has loads of multiballs and I love that game so much fun to play and so immersive, I know there are haters on it but maybe you have not really got into the Hobbit to appreciate it.
Looking forward to getting and playing GnR.
