Granted that Clash of the Titans (1981) was awful. I've never seen Alexander or Troy, but Jason and the Argonauts? It is a true classic! I've watched it loads of times since I was a small boy. Nicholas Wulstan "Nick" Park says that it is what inspired him to become an animator.Hearing some of the praise in this thread for movies I thought were awful when I saw them makes me think that given enough time anything becomes a classic.
