ANSWER:

Repent to Allah sincerely and never do that again and you must not listen to anyone while being disobedient to Allah. Politely but firmly, without being disrespectful to your parents, refuse to go from next time.

I recently watched a movie which was based on falsehood and the biggest of them being shirk, even though I knew that this movie is against my belief and I didn’t wanted to go but my father insisted to take me. I know that it is a sin but to what degree it is the disobedience of Allah and what would you advice me?
