Attempts to be a sci-fi mystery-thriller trying to catch a time-traveller. Not a bad idea but pacing could be better and not enough closure.

Moderately funny but can be dark and serious in parts. Measured and balanced in most respects. Entertaining.

Mildly entertaining but meh.

Overly simplistic plot and themes, lacks style, but is otherwise not a bad lighthearted action film despite the serious subject matter.

Post-climate-change-apocalyptic premise. Uninteresting with too many annoyances.

Good production. Mostly well-paced story in the spirit of the first two films even if it has a few problems. Dark and gloomy.

Moderately intriguing. Pacing can be better but no big deal. Nicely edited. Amusing score. Go Min-si is flipping nuts. But in a good way.

Tries too hard with the action and gore, but an acceptable conclusion. Overall, meh.

Moderately dark and comical. Both the black comedy and action are very measured. Solid film in every respect with decent pacing.

Mystery with elements of a horror-thriller framed in a fairy tale–like story. Nothing bad. Just flat. Plotting and themes are a bit clumsy.

Implausible plot progression. Constant action with decent cast and performances can’t save it.

Solid writing, performances and production. Tight plotting. Surprisingly good, even if one doesn’t like the genre.

Predictable. Lacks action. Lacks tension. Disappointing no matter how much one loves Jessica Alba.

Tight action-comedy. It is a bit silly but it’s meant to be. Nicely lit and shot.

Not a bad effort but nothing special. Could have used other fairy tales since there are over 200 to choose from.

Starts strongly enough. Relies on the cast to hold it together. Final act could use better writing and way better execution. Meh.

Ninja family vs rival clan. Nicely shot. A few points regarding characters and conflict can be better, but intriguing and entertaining.

Not bad but could go further with the paranoia and suspense. Think of it as a version of Agents of S.H.I.E.L.D.

Solid action-mystery-thriller drama with decent pacing and signposting. Moderately intriguing. Entertaining.

Not intended to be a fast-paced action-packed thriller. Steady pacing. Not overly stylized. Impersonal but still interesting enough.

Tries to be some sort of action-thriller but fails. Too many conveniences and inconsistencies. Can skip.
