As Prime Video becomes Batman's new streaming home, the animated feature film Merry Little Batman arrives there to ring in the holidays. Featuring an all-star cast and distinct animation style, the movie is a fun-filled adventure geared toward younger audiences that may not be every fan's cup of tea but brings its own solid take on the Batman legacy. Reminiscent of classic European animation, Merry Little Batman works best when it downplays its manic tendencies and focuses on its sentimental undertones.
