I think part of the problem here is that the search for Luke leads to nothing actually meaningful in the end

So a film in which the plot is about finding someone has an ending that isn’t meaningful because they find the person the plot revolves around?

it has no impact on the plot

Finding him was the plot…

not in this episode anyway.

The impact of finding him will reverberate through the rest of the trilogy yes but the film had an objective of finding this person and it accomplished that.
