Imagine Robert Frost traveling along a path in the woods and finding a fork. On the right, the more beaten path. On the left, the proverbial “one less traveled by”. He chooses left and moves forward. But after a bit, reconsiders and returns to the fork. Then chooses the right and, again, proceeds further into the woods. Unhappy with his choice, he returns to the divergence and resumes his stroll on the left. But he is no happier on the left than he was on the right and retreats again, this time with certainty to take the path on the right. After multiple repetitions, he wanders aimlessly in a circle at the fork, traveling in no particular direction at all for any length of time. Not a particularly compelling poem had his most famous work followed this trajectory.

But this is a pretty fair metaphor for “Tomorrow”.

Like an aimless wander through some woods, it might not go anywhere meaningful but that’s not to say that it’s entirely unpleasant. There’s some marvelous casting. In his previous work, Rowoon has demonstrated a relaxed and natural vibe and he’s got a pretty full toolbox of skills to capably lead any tentpole drama. Kim Hee Sun is a terrific match for the role of Goo Ryun. Kim Hae Sook is a welcome sight in any production.

The concept is a refreshing mix of grim reaper and the Hollywood blockbuster “Men in Black”. Rowoon’s Joon Woong, through an unlikely chain of events, finds himself working as a not-yet-dead grim reaper assigned to the Crisis Management Team, a special unit that is tasked with helping souls on the brink of suicide. It’s very dark and heavy stuff, but the production manages to find some lightness and humor. Joon Woong’s childlike, adventurous personality aids the entertainment quotient enormously. There’s lots of Barry Sonnenfeld-style touches too like Kim Chil Doo’s multiple mute appearances. And the production value matches the need for outlandish hair and wardrobe, otherworldly sets and occasional specific effects.

The photography and OST aren’t award-winning but neither do they detract.

And where “Tomorrow” takes an approach as a procedural show, it has some exquisitely outstanding episodes. Several of the episodes in the first half of the series (which has a more procedural bent) are powerfully emotional. The characters and guest acting performances by the targets of the Crisis Management Team are wonderful. Rowoon’s interactions with these characters show off his acting strengths.

But this production can’t stay committed to this path. It’s got a serial narrative underneath and eventually the procedural approach dissolves and things go backward. Or south. Maybe down? It’s not clear.

Among the most problematic elements are some very awkwardly introduced backstories. There’s also too many of them as Kim Hee Sun’s Goo Ryun, Lee Soo Hyuk’s Joong Gil and Yun Ji On’s Ryung Goo characters all get period piece backstories. But none work well. Goo Ryun’s is in fragments that don’t fit together. Joong Gil’s seems to be threaded with Goo Ryun but it’s so haphazardly edited in to the present day storyline that it becomes an unwelcome distraction. The worst, however, is Ryung Goo’s episode-long slog well past the halfway mark. Had it been shorter and earlier, it’s conceivable it could have contributed. But Ryung Goo’s character is not exactly a breath of cool, crisp mountain air to begin with and spending an entire hour in a historical era where everything goes badly and then even more badly and then just goes downhill at an accelerated pace is simply unpleasant. Even had there been an overwhelming positive outcome in the present day, it’s not enough to balance out the misery of the backstory.

As for the present day, Joong Gil is a mess all-around. The character is dull. Lee Soo Hyuk’s portrayal is unwaveringly one-note which is an expression of no expression at all.

Kim Hae Sook has some lovely moments early on in the series, but as the episodes progress, she appears less and less frequently.

Rowoon’s Joon Woong is a solid character and has a perfectly good setup where his adventures put his mother and younger sister into a precarious predicament. Like with so much else though, after a promising start, the focus wanders away in other directions.

Most problematic is that the main characters, whether it’s just Joon Woong and Goo Ryun, or if the main characters also include Joong Gil and Ryung Goo, they simply don’t fit well. Chemistry is an overused term as professional actors worth their salary should be able to fool an audience that they genuinely have feelings for each other. But a lack of chemistry is precisely the most apt description of what ails these group. The characters just don't fit together and, frankly, "Tomorrow" doesn't seem to care that they are only somewhat interesting characters separately and wholly unconvincing as a team. Although some blame might fall on the actors or casting, more of it should be borne by the writing which introduces too many sideplots and the directing which invests heavily in creating a modern, quirky and fantasy setting and then jettisoning it to play it safe with worn-out themes.

“Tomorrow” has enough bright spots to recommend it but expectations should be tempered.
