Adam West and Burt Ward return in this cartoon version of Batman.
As other reviewers have noted, this short lived series is damaged by a silly creature named "Bat-Mite" and the network demanding that everything be kept very kid-friendly. 1966 live action Batman was made for both for kids and adults. So basically, if you enjoyed 70s cartoon Superfriends you will probably get a blast out of this as well.
In 1977 it would have been out of the question for Filmation to re-start the 60s live action series but when watching "New Adventures" the presence of West and Ward almost feels annoying because it comes over as a wasted opportunity - if the guys are here then give us a live action version!
Filmation was very skilled at making live action super hero shows - see Shazam! (1974) - so we can only wonder what things would have been like if they did a live action take on Batman a few years before 1977.
But again, if you liked Superfriends then you will probably get a blast out of The New Adventures of Batman (1977).
