Batman & Robin (1997)
I unabashedly love this movie. It’s got a terrible, pun-laden script, hammy acting, a cast evenly divided between great actors slumming and future has-beens, and some of the strangest day-glow-gothic production design I’ve ever seen.
It’s one of the first contemporary non-animated films I saw as a kid (on VHS, naturally) and to me it will always represent that vaguely-remembered time in the late 1990′s. It’s a horrible, compulsively-watchable high-camp classic.
