This film gets a lot of praise, and while it is well done and surely entertaining for the younger audiences, anyone who has seen a fair number of films besides the usual latest pop stuff at the theaters will recognize that every single thing about the film is taken from earlier movies. "An ode to the earliest days of cinema" it may be... in fact, every idea, premise, theme, every mood evoked, etc. has been used before. And that gets pretty boring after a while.
