I just started watching Sherlock and from what I can see so far I think it would make the most sense watching it in chronological order.
You can watch all UK TV channels BBC ITV 4OD & US sites like Hulu online if you install a VPN on your laptop or tablet/TV. easy to do and unblocks all regional sites worldwide

well only you can decide such things its the same theory as do i want a cup of tea or do i just go to toilet have to focus more on what do i want to be doing right now!!!
You'd really appreciate the show if you watch them according to how they aired.
Just for season 1 and 2. I want to be wholocked. the only episode ive seen is a study in pink and i want to know if i have to watch it in chronological order for it to make sense
