Seriously when Dick Grayson references the 80's Kurt Thomas vehicle to nowhere "Gymkata" the rest of the film could have been deeply mediocre and still be totally worth the price of admission. However, Chris McKay and 9 other writers load this fourth wall exploding reference machine with every conceivable Easter egg back to The Batman's first appearance in "The Detectives" comic books in the 1930's. Highlights include recent references to the idiotic "Suicide Squad" and moldy references to the departed Prince's 1989 "Batdance". McKay's true genius will turn out to be crafting a movie that all but requires multiple viewings to get the most out of the dense but fast moving jokes. As a motion picture, it's also not bad. It doesn't fully have the heart of "The Lego Movie" and you can see the ending coming as far away as Arkham Asylum but the plot is a serviceable enough platform from which to launch more quips and 4th wall breaks than "Deadpool". The script also offers eminent quotability and you'll be sharing your favorites with your friends until people unfamiliar with the film tell you to shut up. In short, if you are a Gen-Xer or older, plan to see it again and agin.
