" Forest " had potential but it didn't really exploit them.

The first episodes and the last ones were actually great. The couple had also plenty of romantic moments and they were sweet and adorable. Their love story was enjoyable to watch especially since both of them helped each other get through their phobias and problems. The big mystery behind the forest was solid too. In addition, the second couple was quite entertaining. Finally, the performances were great from all actors and actresses, though the bad guys tended to overdo it sometimes.
And yet, somehow, the drama ended up boring. They didn't really handle the story very well and most of the episodes were tiring if it wasn't for some entertaining moments here and there.

So, overall, five out of ten.
