The Day of the Doctor is an excellent 50th anniversary episode of Doctor Who. Not only does it pay loving tribute to 50 years of television history, the feature length presentation moves the overall story along and even rewrites what came before.
The cast is excellent and while Elizabeth I's accent has a hint of Welsh coming through, the story moves at a pace that you barely notice it... And to be honest, I was too busy geeking out at David Tennant's return and John Hurt's heavy take on the Doctor to notice.
The video quality of the Blu-Ray is top notch in both 2D and 3D (more on that in a bit). While some have noticed the video has been slowed down resulting in a "judder" picture, my TV hasn't shown any sign of that and I have no complaints whatsoever.
If you have a 3D setup, you'll be in for a treat. Unlike a lot of content lately, Day of the Doctor was filmed natively in 3D and not converted afterwards. As such, the stereo effect is very natural and easy on the eye. Less sparkle and more immersion.
The bottom line is that this is an excellent episode on an excellent disc - a must buy for any Doctor Who fan.
