Memory was well done, except for the most asinine, ridiculous editing flaw and some shaky camera. In every episode, a scene would have a hiccup. They would say a few lines, and they would instantly repeat the sequence. It served no purpose, because it was not the ML having an Alzheimers moment. It would appear at random, and would involve other characters, as well. It felt as if the viewer was having a brain fart or Alzheimers moment.

Lee Sung Min did a realistic portrayal of a man being tested by his creeping illness and the conspiracies popping out of the woodwork. The writer made Park Tae Song (...LSM) earn his pay. Lee Jun Ho and Song So Hee were excellent as Jung Jin and Sun Hwa, the guardian angels to Park Taek Seo during his good or bad times. The Memory castlist was perfect. The main and supporting actors gave memorable performances.
