This drama was quite excellent, 10/10. Yes there are issues such as quite a few dumb decisions by our MCs and some semi obvious plotholes, but still I find that it's much better than dramas such as Master's sun & DoTS, maybe even slightly better than Pinocchio. Honestly I did not feel that the ending was rushed at all, it had everything that's important. I especially liked that every 2-3 episodes there was a little breather from the melodrama. Probably this is the most underrated drama that i've seen thus far. Shin Mina was even prettier than usual, it seems like she gets prettier every year, her figure especially is quite something, if real...

Normally I don't like watching melodramas, but I don't regret watching Tomorrow with You for a second, I'll just need to watch a couple of Running Man episodes to get over it.
edit: Now I'm a lot more experienced with kdramas than at the time of writing this review, this is definitely not a melodrama, it just has a little melo flavor.
