Netflix has the most, best movies out of all the streaming services

If you can only afford one streaming service, maybe this study will help you decide.

Based on the Rotten Tomato scores of all movies available on each of the big streaming services, it looks like Netflix has the best selection of movies, according to a study from Streaming Observer.

Compared to Amazon Prime, Hulu, and HBO Now, Netflix has the most movies that are "certified fresh" on Rotten Tomatoes, which means they have a steady score of 75% or higher and have been reviewed by a significant amount of critics and Rotten Tomatoes users. Of Netflix's 3,839 movies, more than 15% are certified fresh.

Hulu has the closest number of movies at 2,336 but only 9.6% are certified fresh. HBO Now with 815 movies is sitting at 4.7% certified fresh. Amazon Prime has the most options at 17,461 but quantity does not equal quality for the online retail giant because only 1.3% of its movies are certified fresh.

All this basically comes down to the fact that Netflix has more higher quality movies than anyone else — 596, to be exact, which is roughly 360 more than both Hulu and Amazon Prime.

The data used by Streaming Observer is from Jan. 20, so it's always possible that this could change. Movies are coming and going from streaming services all the time, and when new streaming services like Disney's anticipated service come along, it'll be quite a disruption for these sites.

Plus, this is all subjective and doesn't take television shows into account. It's really all about what you're interested in watching. Not everyone wants to watch the best movies all the time. Sometimes you just want to watch King of the Hill, and you can only get that on Hulu.
