What is the meaning of 母を恋はずや in the film title?
Edit: the meaning of "恋う" according to the dictionary is "romantic love" as in "koi suru". E.g. http://dictionary.goo.ne.jp/srch/all/%E6%81%8B%E3%81%86/m1u/ says "特定の異性に心ひかれて、その人を思い慕う。また、特別な人物や場所などを強く慕う。恋する。" So my query is partly about the grammar but also why it is 母を恋する. I can't believe it is some kind of incestuous relationship.
