Psychedelic acid fun made in a time when Batman could be colorful and childish. If crazy people actually would go around in costumes and try to kill people off they would probably look and act more like this than in any other comic book adaptation as they all look like they have run off from a mental institution (and that includes Batman and his gang!). Hard not to laugh of the over-the-top story and acting though.
This isn't really as good as the TV episodes, which were really great, with cameos by an amazing list of guest stars too long for this space, and snappy dialogue full of double-entendres. This film sacrificed much of those great elements and dialogue nuances in favor of showing off all the bat-toys, that were soon to be marketed by Corgi (UK) and many other companies. But oh, how I loved my Corgi Batmobile!
