Cons
Con Recommendation engine is not great
It rarely hits that feeling of "YES! So glad it recommended me that movie for how I'm feeling now."

Not so easy to find where to watch a movie of choice as there are now so many different streaming services and one rarely subscribes to watch a single movie.
