Batman was a huge formative movie for me. I wore out our VHS when I was kid watching every single goddamn day after school. I'm can't be too sure, but I think this Batman was my very first exposure to superheroes. To this day I still love that iconic black and gold Batman logo; some kind of triumph of graphic design there. Danny Elfman's score is pretty easily his best work too. Other than those details though the movie is so hit and miss, and I'm feeling the same as Amy in that it diminishes in my eyes with every viewing. Burton laying down some real stankin' cheese here...
Superman: The Movie has its flaws as well, but is the obvious choice for entry into The Canon of Great Films. Superman is realized in a really full and satisfying way; obviously owing a great deal to Reeves. Superman as an ideal has been mightily abused in uncaring, crass and juvenile ways by MoS and BvS. Superman The Movie just has a real loving and faithful portrayal of the big ol' lug, and I'm glad to revisit in the wake of the bummer that is Batman v Superman. My man is simply earnest, good and helps people. The other guy is a puffed up snapper of necks wrestling with responsibility. Off topic?
Anyway Superman The Movie isn't perfect, Devin really nails it with his frustrations, but it's a legit pillar of Superman's cultural status. Not to mention Donner writing the blueprint for all comic book movies to come. Into The Canon!
