Oh, it's so interesting! It seems, you created a new vocabular. :) To me, "any noun +holic" sounds awesome, because I like to play with a language. It reminds me the poem "Jabberwocky" from 'Alice in Wonderland'. And I really believe you can use the term movieholic, if you write a novel, and your character explains the meaning of this term. However, there are only some words with ~holic. For example, workaholic (the persons working too much). Good luck with your studies! :)
