Half the time the dialogue is dubbed in, and at certain points it's painfully distracting.

In the film world, sometimes dialogue isn't recorded, or the quality is so terrible that it is re-recorded in a studio and added in post production. It's called ADR, or Automated Dialogue Replacement. Most people never notice it if it's done well, but I gotta tell you, this was bad. You shouldn't need ADR in simple scenes between two people in a quiet room. It's almost like the sound guy called out most days.

Having said that, this was a fun PG-13 watch. Adults should stop giving it so much praise tho, it's for kids. And I agree that Luis Guzman is grossly miscast. You would think tons of actors wanted that role, so why Burton cast him is beyond me. And I love him in other things.
