"I don't understand why Zendaya is getting so much praise, when she was only in the movie for 5 minutes "

Because those 5 minutes created a dimensional and relatable character. Who is a badass woman of color. IDGAF if she was only in the movie for 60 seconds! She deserves every award she receives because it only took her 5 minutes to create a character that normally takes an hour. Next person to say some shit is getting punched in the throat.
