Spontaneous checks out as a movie that starts with a big blow. The film carries a subtle mood from start to end that can either makes you feel bored or can create a nice atmosphere that you will get blend into. Katherine Langford and the other actors have delivered a good performance. The tension of the movie doesn't let you lose track and keeps you in your seat all the time. overall Spontaneous is a good addition to the list of teen drama movies that you can try at least once and it will not disappoint you.
