this is basically how i see it
Hollywood has a budget for making moves (i say hollywood just to reference movie central). And that budget has to be spent somehow. You have your large acredited directors and producers like stephen speilberg, christoper nolan, m night shamalyan, etc. but they cant even use up all the budget because its so large
so then they have to get rid of that money some how by giving it to guys like Ice Cube and jessy terrerro to make horrible movies like Are we there yet or soul plane. the faster they spend that budget, the more they get the next year. Its crappy movies liek this that balance out hollywood
and the last fast n furious wasnt THAT BAD... i mean they could have used better CG, and actors, and location.... and story line... hmm now that i think about it.... maybe it was kinda bad... oh well... lets just think of it as keeping paul walker and vin deisel employed
