Here are some cons and pros:

Cons:
-The acting is mediocre. Not the worst, though.

-It's way too short for it's story. We don't even know what happened to Denis! Why is he the way he is?
The story wanted an action but it didn't have the time for it.

-The characters are kinda dry.

Pros:
+The ending broke me, in a good way. (But it ended way too soon.)

+On the other hand, when it comes to fluffy love story it's really good - perfect example of "short and sweet" - 10 episodes with like 12 minutes of action.

Overall: good drama, there must be a mood for it.
