Raimi was "convinced" to use Venom and the Stacy's by corporate decree. One could easily read between the lines in those interviews where he said things to the effect, "after listening to what the character was about and their ideas for the character I found Venom to be an interesting character"[paraphrase]. When prior interviews had him explicitly state his non-desire for the character.
If he had done the film he wanted it not only would've been deeper on the Harry/Peter story but would've had Vulture in some capacity.
I'm confident that if Sony and Avi Arad allow him to make the movies that he did with Spidey 1&2 then we will have a great 2pt story. However, with $50m already tied up in Tobey I see executive oversight as being very real.
