Good job! :)

Thank you for correcting! Is it possible to get explanation in english? Much appreciated 😊

There is a slight difference between the two words.
観る　means "to watch"
e.g. 「わたしはテレビを観ます」
見る　means "to watch" plus "to see" /"to look"
e.g. 「わたしは星を見ます」
Actually, 「映画を見る」is grammatically correct. However, 「映画を観る」looks more natural to native speakers. I hope this will help!

Thank you again. This helps a lot!
