Predicting a show's IMDb rating

The binary decision regression tree model that is in the left makes a prediction of determining the IMDb rating in a given show in a streaming service. The binary decision model shown has a max depth of 5. The binary decision model has a mean squared error of 1.1293162481417969 for the training data, and a mean squared error of 1.320551038657345 for the testing data. The mean squared error of both the training and testing data gives us the information that this model is reliable since it is not overfitting. This model also covers every potential streaming service a show can be in.
