Not really spoilers but:
I didn't hate it and after the S3 i had like zero hype for this special so it's beautiful. It's not what i wanted maybe, i wanted modern Sherlock after two years and curls and answers, and it's not perfect but it was good, beautiful, i liked it. And i liked immediately, not after a some rewatch like some scenes of s3. Martin was amazing and will always be a John Watson's girl and to have a new Reichenbach falls (even if only in the mind palace) where are the two of them ("There is always the two of us") makes me happy. I'm still worried about s4 and the baby and the crime (that i hated in s3) but damn i missed you guys. So much.
