Can’t argue with that, you know better what works for you.
However, make sure you don’t have an availability bias when you compare the prediction accuracy of the two. If you can recall only two or three times when Rotten Tomatoes was better, it might be the case. But if it has been better tens of times, then it might really be the case that Rotten Tomatoes suits better you preferences.
Rotten Tomatoes can be analyzed in more depth, but given the criterion I worked with and the goal of the analysis, I found no reason to do that.
Thanks for the taking the time to write a response!
