Adam--you are not Jack Black! Just be yourself
We get it...you can mimic Jack Black's voice, gestures, and mannerisms. That doesn't mean you should do it, let alone do it for every role.
There is only one Jack Black and I actually can't stand him. He's nauseating. That means that every time you mimic Jack Black in your roles, you're turning off others who also hate Jack Black.
Conclusion: find your own voice and shtick. Quit copying a crappy "actor."
