The new season of Elementary premieres in a few days, and I'm so excited. I just finished marathon-ing the first season and it is now my new favorite TV show. The show is a modern adaptation of Sir Arthur Conan Doyle's famous fictional detective, Sherlock Holmes, set in the US. There are some controversies regarding this series since BBC also has a TV show 'Sherlock' with the same concept. I personally love and enjoy both of them, and I don't understand how many of the fans loved one and hated the other.

First, I think these two series are actually very different. Sherlock only has three episodes er season. Hence, each of them is very complicated and detailed. The plot development is nail biting with jaw-dropping twists. Elementary has 24 episodes in a season, and all but four are separate cases with no connections whatsoever between them. It is simpler, but makes up for it by not making their fans wait nearly two years for only three episodes. What bores you out of Elementary is actually the overused plot twists. After the first three episodes, you will realize that the first, second, an sometimes third suspect is in fact not the criminal.
For acting, I still think BBC's Sherlock is better. They also have wonderful casting - made of very good, renowned actors. I especially liked the three important characters; Sherlock, Watson, and Moriarty. For Elementary, my favorite is without doubt the Watson played by Lucy Liu. She is a very subtle actor and I love every scene with her in it..

Generally, Sherlock has more fans and viewers than Elementary. It is also considered more successful. However, what hooks me to Elementary is its approach to equality and representation. Elementary took the liberty of changing the sex and gender of John Watson into a cis female. She is also a woman of color. Unlike BBC's Sherlock, which is made up of almost completely white, male characters, Elementary has a diverse (thus realistic) cast. There are Asians and African-Americans playing major roles (not background characters or props). The women on the show do not exist as plot devices for men, but are deep characters with interesting developments. The show also has a trans woman character who is played by a real trans woman.
In conclusion, Sherlock is better in terms of storyline and acting. Elementary is simpler and aces in its modern social representation. I think both of them are great in terms of set and costume design. The set of BBC Sherlock's apartment is very detailed and elaborate - as if you can see the character's personality from it. Elementary's Watson has a neat wardrobe - pretty, practical, and modern.
