I initially left a positive review but came back to change it.
I think the game has nice puzzles, investigating the mysteries is challenging while not too hard if you just read and think about it.
However there's one very important detail that broke the game for me mid-play: Your choices make no difference at all.
Halfway through the game I noticed that no matter what you choose for character portraits, who you accuse of a crime, who dies, who is arrested: it makes absolutely no difference in the game. You will not get penalised, and reality will just conform around what you chose. Anything you do will be correct. This is immensely dumb to me, removed all challenge from the game. You will never know if your deductions were correct or if you put the right person in jail.

Very Enjoyable - open world fun, lots of characters and places, logical puzzles, imaginative stories.

But Annoying - frustrating fights (once you are shot, you freeze up and rarely get away before being shot again, to death. I left 90% of the fights options untouched as they were not fun) some puzzles without enough clues to solve (guessing who is guilty is not a fun game) and the end felt unfinished (the options don't stem from clues and I don't remember where we got the clues they provided, and the locale is full of poor graphics like repeated bushes, flat flowers and square edged paving stones.)

While it is easy to remember the annoyances, I thoroughly enjoyed playing it for 20 hours.

Not sure if Sherlock needs a somewhat open world. It's nice but the linear cases of Crimes and Punishments were more enjoyable. The fights are always the same. The cases were really good.
