As for this particular series, I have to constantly remind myself that it's pretty much just absurdist fanfiction. Although I think Downey Jr.'s performance is impeccable, I find the interpretation of the character to be totally annoying if I think too hard about it. It's mostly the unkemptness that gets to me. Clean-cut Holmes all the way for me.
I'll still watch it and I'll still probably like it, I just have to disconnect from the Holmesian part of my brain.
SOLI wasn't a favorite story of mine in canon, but Jeremy Brett doing straight up Victorian boxing in the Grenada adaptation is so unforgettable it's one of my favorites now.
