Be aware of what you are typing, as there are some typographical errors here. In any case, I will explain some of the differences of these interrogative pronouns. どう = How ; as in your example: "How is the movie" えいが　は　どう　です　か？　(keep in mind, when writing Japanese text, you don't ever space it out like this, but since I am writing completely in Hiragana, I am spacing it out so you can see it better) Also, the word for interesting should be written as おもしろい どんな = "What kind," not "how." In some contexts, どう and どんな can function similarly, but not always, so keep that in mind. どれ = "which one" for example: (as you point a finger at various clothes) どれ　が　すき　です　か？ (which one do you like?) A noun can NOT come after どれ. どの = "which" and a noun must follow immediately after. For example: どの　シャツ　が　すき　です　か? (which shirt do you like) I hope my explanation helps to see the differences between all of these. If you have further questions about the grammar, please let me know.
