I loved it.... And I think the strategy is an interesting one... The average audience member and movie fan doesn't know the history of Spider-Man. They have no idea who Venom is and the trailers are doing a wonderful job of hiding that fact. Who knows, this could be a big mind-F***
They could be showing us Sandman stuff and end up having him only be the setup for the big showdown with Venom. And when that happens... they could have it end in a huge cliffhanger involving Mary Jane (Which Venom has often done dispicable things to), leaving us all salivating for more and setting up the final film.
Anything past a fourth film would just be stretching it a bit thin I think. And it would be a nightmare to keep the cast. I see it ending then for at least a decade only to come back with a different actor so that we all can compare him and his film to the old ones with nostalgic eyes...
It will be like Superman eventually or Batman... I have foreseen it... :emperor
