I ordered the FP5 after using my OnePlus 3T for nearly 7 years, so I imagine it'll be OK on that front, given I'm switching only due to issues with the USB port and power button.
I enjoyed the films more than the books. The books after the first feel like the author had a good idea, but didn't know what to do with it. The films tidy it up nicely
And the movie is the adaptation of a Stephen King book
