Sherlock's Lestrade is definitely the best version I've ever seen. It recognizes that Lestrade isn't STUPID, just like Watson isn't. Admittedly, there's a lot less to go on, but I agree that Lestrade is probably a perfectly competent police officer, who just can't match Sherlock. Hell, when Sherlock himself compliments you as the best in the police force, you have to have SOME redeeming qualities, and that shines through in this adaptation of his character.
Yes. Yes. Yes. Agree so much. Lestrade gets more credit in this adapt than in others. Although that's not too hard. The fact that he's a D.I. shows that he has to have some skill for his job, so he can't be completely reliant on Sherlock. Plus there must be plenty of other cases that Sherlock deems himself to unimportant to solve himself that Lestrade has to solve himself. Sherlock's just on another level to those around him so in the adapts the characters around him tend to have over exaggerated flaws so the audience empathises with Sherlock's frustration. I like how this adapt also shows that he isn't just putting up with Sherlock for the sake of solving cases.
