The story is good and keeps you interested, the overall atmosphere presented in the game is good too. There are a lot of puzzles, just like the Professor Layton series, but with Prof Layton, you are compelled to solve most of the puzzles before you continue on and finish the game, with Hollywood Crimes, you're pretty much encouraged to beat the game as quickly as possible, it only took me 3 days to beat this and I'd probably only solved 40 of the 140+ puzzles. Then once you've beaten it, you don't really have any motivation to go back to the puzzles you've not completed.
I personally expected a lot from the game. The concept of the story was nice but far to short. A lot puzzles get repeated a lot (of course it does get harder each time). And with a lot I mean that I think I saw some puzzles 7-8 times if not more. Also the people on the TV show repeat their sentences a lot which eventually might get annoying to some people. This all gives me the feeling the game was rushed.
For the price I see it now on Play I do say it is worth the money but don't expect a lot of it since you will have finished the game pretty fast.
