Spiderman has always been too campy for me. Although I find all the Marvel heroes to be very campy and lame, but that doesn't seem to be the consensus for some reason.
I'd rather watch The Flash or (serious) Green Lantern in a movie before another Spiderman reboot. I hope they make one.
+1 to pretty much everything you said, with an exception (for the most part) for X-Men, regarding Marvel. I did enjoy the 2011 Green Lantern movie, though I know that bucks with the general consensus opinion. It was entertaining without taking itself too seriously, and I love being able to recognize locations where a movie was filmed.
