IMDb shows a question mark 9 out of 10 times.

Good concept, but missing the Rotten Tomatoes Audience Scores, which is the only thing I use really. Critic scores are pretty useless to me.

Metacritic ratings do not work well. They take too long to load and some don't ever load; it seems to be even worse if you're not using Netflix in English. Also, it would be nice to color-code Metacritic ratings as done in Metacritic.com (red, yellow, green)
