My favorite movie is action movies.对不对？

My favorite movie is action "movie"

不对 .My favorite movie is XXX(电影名字）

应该是 Action movies are my favourite type/kind of movies.

My favorite movie is action movies.
当然不对了，is怎么能对应复数的movies.呢？

不对，应该是My favourate movie is the action movie.或者My favourate movies are action movies.

我也是个学生啊，我觉得首先is应该加名词单数，这里是肯定错了，但是 action movies是指一类电影，是不是应该用kind of 来代指种类？

如果是is,后面当然不能加movie"s",应该是my favorite movie is action movie.
