I feel John T. Cucci is not convincing

John T. Cucci as Foley Artist in Teenage Mutant Ninja Turtles (2014) made me pay attention more than I expected. For me, it does not feel very real in many scenes. Some emotions are too simple, and I cannot believe the character enough. Many moments pass very fast, and I do not remember much after them. I do not hate it, but it did not pull me into the story. Maybe other people will like it more, but this is my feeling.
