I occasionally (frequently?) watch very silly movies on Netflix. Wikipedia entertainingly classifies this as "family horror," which means it's aimed at tweens and the horror is pretty non-threatening.
The main character is Kelly Ferguson, a teenager co-opted into babysitting Halloween night when she would far rather have been at the party where her crush was. Along with this assignment, she holds the memory of having seen monsters coming from her closet when she was five. The two things are of course connected.
Reviews have been mediocre, but while it's unquestionably silly and possibly a bit obvious, I found it mildly charming and I'm totally okay with them making being-a-nerd cool. Disposable but fun.
