It wasn't even the obvious shots of cabs, because Sherlock couldn't know about that. It was that the first case was about some guy who got in a cab and hadn't seen anyone since. It wasn't that hard of a deduction from there, and I kept wondering why the fuck Sherlock hadn't thought about any of this or why, when he connected it to the traveling, he didn't go immediately to the cabby, not the passenger. You can't present someone as brilliant and then have them make really dumb mistakes.

From the first shot of the second case, with the yellow writing, I knew they were going to go for stereotypes, and they did. The third episode is actually better on terms of mystery but only because Sherlock is the only one with most of the clues and it get's visibly more dangerous at the beginning.

The actual Arthur Conan Doyle Sherlock kinda annoys me, because again, he's presented as brilliant and while he is, because Watson's narrating I never notice what Sherlock notices and I feel like that means Doyle and consequently Sherlock can solve mysteries out of thin air.

So yeah, I love the characters and the conversations, so I watch for that.
