I've heard the arguments for switching to binary choice (netflix also did a big writeup about it), but I'd still prefer the ability to give a bit more nuance in my rating. It feels weird giving a movie that is okay and a movie that is excellent the same rating.

Rotten Tomatoes goes further to emphasize the "love it or hate it" dichotomy - they display a ripe red tomato for a movie with a rating of 60 and a splattered green tomato for a movie with a score of 59.
