Why didn't they continue GISS as an ongoing car action franchise ?
The GISS remake isn't great, but it made money and should've been continued (and still can be continued, but I greatly doubt if the producers could afford Angelina, who they got cheap on this film) as an ongoing franchise, with the success of the Fast and Furious films.
Any sequels wouldn't have to be about stealing cool cars again, but feature something else car racing action related.
