I believe it's because it's VERY violent. And Odeon are saying by not showing Rambo means they can show other family films!??!
It's an 18 for a reason. Yes it's violent but hasn't Sweeny Todd got some gross out throat cutting. Sweeny is a mudering loon yet Rambo is killing evil, murdering Burmese army loons.
Odeon are being facists!!! Rambo is a great film, chock full of action. It's just a shame that you don't get to see too much Rambo, seeing as the Mercs he has with him have to get some of the action too.
