Don't buy this if you're not a fan of Dan and Phil. well, you can, but you won't understand much of it. the only thing that will happen is that you won't understand the jokes, think that this is for kids and leave a bad review. we don't have time for that. if you've never heard of Dan and Phil before, spend your money on something else.
now if you HAVE heard of them, and like them (or know someone who does), definetely buy this. it's a masterpiece and you'll have a good time. you'll have a good time whether you're 12 or 30. I went to the show twice but I'm still so glad that I have the dvd now, so if you went to the show or not, you should definitely get it.
