Simple amount of screen time doesn't really mean much. Heath Ledger's Joker, probably the best supervillain performance to date, had less than 11 minutes of screen time in a 152-minute long film.

That being said, the best way to do Venom would be to introduce the Black Suit during the next film, have Peter reject it near the end, and have it bond with Eddie Brock as a sequel sting. That gives Venom a full movie to do his thing.
