How can we interpret biplot? This is not a question as such but more likely to be verification (enhancement) of my current understanding. With the thought that it may help future visitors as well, I am taking liberty to make this post.



Question


Is the interpretation mentioned in attached image correct ?
As per my interpretation, Movie A doesn't seems to have much Action, nor Drama. What does that mean? Is it boring movie or what?
I would like to give some intuitive name to PC0 and PC1, what seems to be suitable name for it?
In short, Answer to your questions:


Yes
Movie A is near to center of the plot. Its the most balanced movie from your collection. (Biplot's center reflects the average of PCA scores: neither positive nor negative). 
PC1 scores are positively correlated with with Romantic/ Comedy  and negatively with Action movies. PC0 is mostly negatively correlated with Drama movies.
