I have watched all the movies but not yet Movie 17 since it will be released on April 20th. (I can't wait tho!)
And I have always liked all those movies I have watched, but I'm a little bit disappointed on Movie 13.
I have also always liked action packed DC movies, especially when Ran's kidnapped/ whatever.That's because I ship ShinRan :"""">
I find their pairing very romantic and cute. <3
To answer the question tho I like Movie 4 the best because of the plot and all.
