Smile 2.
I wasn't a fan of the first film. It sort of lost its way midway through and I got very bored of it, and didn't finish the movie.
But Smile 2 was much better. I think that's largely down to Naomi Scott who I believed was the person she was portraying in the movie. She's a good actress who made her natural performance compelling.
I gave Smile 2 - a respectable 7.5 out of 10.
