I'm going to be one of the few to actually stick up for Apple here, and say that it's £2.49 rental charge is good value. Ok, sure, at the moment you can actually buy this film from a well known online store for £2.99. But, I for one am getting really fed up with several hundred dvd's taking up so much room in my cupboard that I watch once or twice and then leave to gather dust, till several months later. At least with iTunes rentals, you get the film more or less instantly, and it takes up no extra room in your house. Plus, if you want to watch it again in the rental period you can.
On to the film, yes, it is great. Not laugh-out-loud hilarious, but funny in places. It is also a good drama, with some great, realistic characters. I love road movies, and this is definitely one of the better ones.
