5 I am Bear Grylls.... Hear me roar!!!!Andorra | 21/06/2011 | See all Andorra's reviews (9)After viewing seasons 1-3 on DVD I thought I'd treat myself to season 4 on Blu Ray, and it doesn't disappoint. The picture and sound quality is a cut above the DVD episodes I've seen before and in some instances it sounds so good, you actually feel like you're there with him. Highly recommended to all fans of Bear Grylls!And by the way, it's a lot cheaper to buy on Blu Ray than on DVD.
