I sometimes use https://www.justwatch.com/ which covers some other streaming services, too plus pay-per-watch (I don't have Amazon Prime but a 1,99 movie is alright) and allow to set your Netflix country as coverage is different across regions. The killer feature for me would be to mark/hide everything I've already seen. Could even be a browser extension. Netflix keeps showing me pages of movies I've seen already.
