"Chew up the scenery" is a phrase that is often used in the entertainment industry to describe an actor or performer who delivers an overly dramatic or exaggerated performance. Although the phrase itself is quite expressive, there are several other terms that can be used to convey a similar meaning. For instance, one might use phrases like "ham it up" or "overact" to describe a performer who is being too flashy or putting on a show. Alternatively, terms like "exaggeration" or "caricature" might be used to describe a performance that is too theatrical or unrealistic. Ultimately, the use of descriptive language can effectively convey the intended message of a performance critique.
