Do you think the final episode could be better? If yes,how so?

In my opinion,yes. I loved the fact that they had a happy ending but the first half of episode 16 could've been better,it was very cliche. I loved the entire series except that episode.

I didn't like the last ep either. 

I think that it would have been better to avoid one more complication and just wrap things up quietly. the last car accident and kidnapping was too much.
