Overall, the plot was fine. Although it tried to wrestle with some deep ideas/themes such as suicide, childhood love, or the inability to achieve one's dreams, the gimmicky three day time travel and the format as a movie didn't really allow time for any development of these ideas.

That is not to say that the plot was bad. Perhaps it was a little superficial, but even so there were quite a few tear-jerker moments when I could actively empathize with the characters. This was made especially easy with the superb acting given by Jasper Liu and Vivian Sung (I honestly wish there were more movies/dramas with her in it because IMO she is a superb actress). The good acting paired with an interesting plot -- if somewhat underutilized made the movie quit enjoyable.

Thus, overall, I would say the movie, by itself, was pretty good. It had a decent combination of good plot, cinematography and actors. Yet at the same time, I was left feeling so much more. With the deeper themes presented in the movie, it left me wondering if the movie could have been more impactful if instead of using the time travel gimmick, the movie instead focused on an adult Wang Zhi Xiang aiding an adult Li En Pei in reconciling her shattered hopes and dreams with reality. With the superb acting of Jasper Liu and Vivian Sung, I'm sure this hypothetical movie would have been amazing. But, alas, what we got was just "Take Me to the Moon", which on it's own merits is still quite good.

Hence, I definitely recommend giving a watch.

(And also, to the gods of Asian dramas, please give Vivian Sung more roles!! She is too amazing to only have had so few roles in her acting career)
