How anyone can claim IM3 was worse than MoS, possibly the worst super-hero movie since Green Lantern or Jonah Hex, and certainly worse than even the prior Superman movie, is baffling to me unless they are just DC fanboys.. which is fine I guess... everyone has bias towards something...
DC is in no way, shape, or form coming even remotely close to Marvel/Disney. DC has one noteworthy franchise in a medium outside comics that isn't borderline MST3K fodder.. (And Dark Knight Rises could go either way...)
I keep hearing good things about Arrow, but haven't watched it as there has never been anything but complete drivel on the CW.. The announced sequel to Constantine is the best decision DC has made in... well... ever.
