I do love the first Ace ventura.
But the sequel is ... disappointing.
All jokes, no substance.
No surprise if he feels tired of that.
I've only seen a few of his other movies. When people had doubts of him playing as Dr. Robotnik, I was like, "Edward Nygma"? "Cable Guy"?
That could work but I really hate how there are so many Metal Sonic in the movies.
It's like playing beat em up where you fight a cool boss in the stage 1 but in the later stages the cool boss became just regular baddies.
It was surprising so many Metal Sonics and Amy beat them up all with ease.
Sonic 4 Rumor: Scarlett Johansson-Type Eyed for Amy Rose

Scarlett Johansson would be more suitable for the role of Rouge. If they're just going to make Amy a girlboss who takes over the film and make Sonic inadequate then f**k you Hollywoods modern standards of female impowerment that's making female characters less likable and ruining movies over it!
Sonic The Hedgehog 3's Biggest Sonic Problem Could Get Even Worse In The Sequel

What we have here sounds like "too many cooks in the kitchen" or "Batman & Robin" kind of situation which I feared will eventually happen in the films.
When the films has so many additional characters that not only do they take attention away from the main character/s but also juggle too many stories for the audience to keep up with.
It's something I fear will happen in Sonic's fourth movie if they make Amy Rose a strong independent woman who is more heroic than Sonic.

I doubt my prediction of him making Metal Sonic will come true, but it be interesting if my prediction is right for a change.
Sonic 4 Rumor: Robotnik to Return

As much as I like Jim Carrey as Dr. Robotnik, I honestly think they should give him a break. Let Sonic 4 be without him and have Agent Stone or Neo Metal Sonic as the established villain. Have Dr. Robotnik at least show up in the mid-credits.
