More TV shows should stick to limited life spans.
They are? All of them? Superman and Batman are universally loved. Perhaps their other characters aren't as well regarded, but I Bats and Supes are on par in popularity with any of the top Marvel characters.
batman had a good run lately with "the dark knight", but the ones before that were pretty bad. mr freeze? it was like bad tv all over again. even the latest man of steel was pretty bad, to me. however, globally it did pull in around $650 mil. i just couldn't stand seeing the entire city demolished worse than even pacific rim. didn't care for the acting and the rocket launches he did when taking off.
but when you look at Thor, Avengers, Thor 2, Iron Man 1-3, X-Men, Wolverine (you could argue his solo films didn't do as well) Spiderman (any run will do but i am enjoying this last run even if electro was pretty badly done) and so forth.
of course they keep trying to do Hulk movies and they should ban any future attempt to try again. daredevil wasn't too terrible but they never should have made the electra movie. so yea, a few poo-bombs in their cellar. the last spiderman movie from the previous series however contained the worst scene ever put into a movie with peter parker dancing like a giggalo down the sidewalk.
as a comic collector i just grew up on marvel OR indie characters for the most part. firestorm was my favorite DC character and i had to giggle like a little school girl to find out you have to scream SHAZAM to get your powers. outside that, we have:
the dark knight, series won 2 oscars.
man of steel - marginal to me but i'll concede to its success.
then we have:
green lantern. i smelled poo bomb the instant they announced the movie cause the comic book always had goofy looking characters. squids in a bubble trying to look like a hero and so forth.
jonah hex
catwoman
various earlier superman movies (richard pryor stealing money?)
and in general, my overall feeling is the justice league will make some money simply cause comic book movies are pretty popular today but as of today (just read wiki) no script, no director, and it even being done now will depend on the success of batman / superman.
it's all preference, to be sure. marvel for some reason (cough stan lee cough) just had the better base of heros to work with.
