What kind of time-travel story is this?

A brief temporal moment, cameo or sequel setup.

A borderline case: the temporal interpretation remains disputed. The mechanism is classified as Cosmic.

Why the archive makes this assessment (spoilers)

On the night Miller's Comet passes, eight friends at a dinner party discover the street now holds many overlapping versions of their house, and they cross between realities without knowing it until Em sets out to swap herself into a better one. The film is about parallel realities and decoherence, not time: the versions run side by side, and the only temporal content is reviewers' mention of the comet's odd effects on time and fan readings of small timing discrepancies between houses. That brief, unconfirmed element puts it at 1 rather than 2.

The comet primarily enables crossings between parallel realities; temporal offsets are not clearly established in the reviewed descriptions, so confirm an actual time component before retaining as time travel.

How Titan works

Titan combines the archive’s quality, audience and legacy base with the significance of time travel. It is an index, not a score out of 100, and is distinct from the FMV archive’s scoring model.

Titan = base × [0.20 + 0.80 × (time-travel score ÷ 10)²]

This film: 105.60 base × 20.8% weighting.

Partial inputs flag incomplete source metadata. Provisional weighting flags a time-travel assessment that remains uncertain; it receives no additional confidence penalty.
