Though inclined toward the plural, I want to confirm whether the auxiliary verb here should be plural.
The best part of the movie is/are the quirks -from smart flashbacks to character twists at the witty set-pieces.
What does that verb refer to? '….the best part…' (and so singular) or '….the quirks…' (and so plural)?
Is is incorrect? How?

Unless you are asking a question, the subject, or what the verb "refers" to you, is always in front of the verb.
The best part of the movie is the subject of is.
What comes after the verb (complements, objects) doesn't affect the form of the verb you use.
