Got these over the last couple of days. Baby Driver is my first 4K Blu Ray and honestly, I'm not sold on 4K. It looks great, but I'm not sure the difference vs standard blu ray justifies the jump in price. I do only have a 43 inch TV, and not one with HDR, so perhaps when I one day get a bigger TV with HDR, I'll be able to tell. REC was an impulse buy whilst I was in HMV today, I love zombie movies (well, REC is infected if you're being pedantic) and the REC movies have been on my radar for a while, so when I saw you could get the first three for £5, I jumped on it. I'd have liked it on BD, but at that price, DVD shall suffice, I can always upgrade later if I like them.
