Sometimes it can be hard to determine on what streaming services a movie will be available. It can sometimes be annoying as well switching between the different apps trying to remember where you saw that title you were interested in watching.
Grepstream is a new search engine for streaming services that enable you (after a bit of figuring it out) to search for specific titles and movies that are available on a specific service. In the link I just shared, you will see a search for Roger Ebert movies that have received four stars available on Netflix.
You can tinker with the search yourself and see what comes up. It can be a bit tricky trying to figure out how to search for specific things, but once you get used to it, the tool becomes quite powerful.
Give it a whirl and let us know if you come up with any lists yourself!
