A great TV show. Of course it contains a huge amount of legendary smartness, yet you'll feel so clever the moment you start understanding what's happening. Glimpsing small clues and anticipating scenes, all by yourself, makes the thrill runs in your veins. I wish I could forget it just so I can see it all over again. Welcome to my amnesia list.

It's okay, but a quite unrealistic which is normal for this genre. Also Sherlock sometimes talks way too fast and it's very hard to process what he saidy and the thing that he's British it doesn't help. Overall, it's all right show, nothing spectacular.

**This series was just excellent! Don't miss it!** What else can I say? Excellent 9/10 = Don't miss it! Meaning stop reading now and go watch it!\ \ You really don't want to be spoiling this one, and it's better to be surprised, so you should stop reading now, and go watch it!\ \ Let me give you a tip for when you watch it - watch it at 0.75 or 0.80 speed, so it will last longer. If you do that you will be thankful you did that, because it does 2 things. 1) It slows down how fast Sherlock is rationalizing so you can make better sense of it, and 2) it makes the whole excellent series last several hours longer and you can get more enjoyment out of it.\ \ But ultimately, what you do is up to you, all i'm trying to tell you is don't miss this!
