Quoted from Rarehero:

It's Wilder. No need to speculate on that one. Like WOZ, it's a whimsical nostalgia-passed-on-for-generations movie. Depp Wonka is divisive and even those who like it don't care enough to buy a pin based on it.

Quoted from Aurich:

I honestly think it's aged badly. It's simply not a good looking film anymore, the sets look low budget and corny now, and the acting that isn't Gene Wilder chewing the scenery is stagey and over exaggerated. If you haven't seen it in a while and just remember the memes and "I said good day sir!" you can watch this scene:

and see if you agree. If you love the movie I'm not trying to be a jerk, just honest about what it looks like. It's really dated. I love Roald Dahl's books, I think it was a fun movie for the time (the Tim Burton remake is a looker but a shitty film, the original might not hold up that well but it's still better). But killer pinball theme? The hype is out of control.
It's already a slot machine, it's an available license, and JJP took it. Probably hoping the candy rainbows would be another WOZ since that one still sells. The hype and frothing over some rumors is peak Pinside though.

Quoted from PanzerFreak:

Be sure to Cliffy your game if you are buying one! Lol
Oompa loompa doompety doo
I've got a perfect Cliffy for you
Oompa loompa doompety dee
If you are wise you'll listen to me
What do you get when don't protect your game
Playing as much as a kid with free credits plays
What are you at, getting terribly lax
What do you think will come to your playfield if you do that
I don't like the look of it
Oompa loompa doompety da
If you protect your game, you will go far
Your game will live in happiness too
Like the Cliffy Oompa Loompa Doompety do
Doompety do
