I went into this with middle-of-the-road expectations and was so blown away by it. Although it took me a little bit to get into it, it really grew on me.

Tunnel had a really good balance of humor and thriller, the time-travel aspect was used really intelligently, and character stories were tied together surprisingly well. That last point, with the characters, was probably my favorite part of the entire drama. I was so impressed with how characters fit into the timeline and into each other's lives.

I was also pretty satisfied with how the mystery was wrapped up. I still definitely wanted a little more — like wanting one more reunion, one last conversation, but overall I thought it was overall really well thought-out.
