If I was to rate the Sherlock Holmes series on season 4 alone, I would give this 0/10 if possible. Benedict Cumberbatch (Holmes) was barely tolerable and the new surprise character was appalling. Without giving away too much, they draw a parallel to who this character is "meant to be like". Sad to say that the performance wasn't even in the ballpark. I found myself biting my fist to dull the pain.

Season 1 and 2 were knock outs and deserve high praise. They were overall, superbly written and acted, well paced and suspenseful. Season 3 experimented and was somewhat of a hit and miss as it shifted to a character drama with broader appeal.

The writers really should have stopped at season 3. Moriarty was butchered in season 4 with a huge fall from acting grace. It's left a stain on most of the cast members. If you love the series, please, PLEASE skip season 4. It doesn't even feel like the same show anymore. It reminds me of one of those D grade TV shows that airs during the day when TV ratings are rock bottom.

Season 1: 9/10 Season 2: 9/10 Season 3: 7/10 Season 4: 0/10 Overall: 6/10
