A prequel set one year prior to the events in Raiders of the Lost Ark, Indiana Jones and the Temple of Doom is a much darker, violent and, unfortunately, less fun adventure movie than the original.
For one reason or another, Temple of Doom is also a much more generic adventure movie than its predecessor. While still a clear notch above all of its competition thanks to first rate production values and Harrison Ford as the Indy, the story could’ve been well passed off as one of the adventures of Jack T. Colton or Allan Quatermain instead. Unlike in Raiders of the Lost ARk, there’s really no iconic scenes in Temple of Doom that would’ve become a part of the pop culture folklore.
Temple of Doom is not a bad movie by any standard, especially compared to the other adventures of the era. But it is a victim of a middle child syndrome, paling in comparison to what its go-getter elder and younger brother have to offer.
