Re: Most disappointing comic-book movie
Spider-man 3. I'd waited years to see Spidey deal with the symbiote and his most tenacious foe in Venom. I got to see the symbiote introduced with the weakest of plot devices and Topher Grace goofiness where a menacing monster should have been.
Of course, SM3 is still light years better than Batman& Robin.
