I salvaged this review, which I wrote in 1999, from IMDB:
A Thin Red Line – Interesting, but much too long, 11 March 1999
Author: Julian Richardson (firstname.lastname@example.org) from Edinburgh, Scotland
There were parts of this film which were interesting, and parts which were beautiful, but overall the film was spoiled by the fact it is far too long. The last 45 minutes of action and accompanying navel-gazing flowed over me like water.
I cannot understand why the film was not cut down to say 100 minutes. I found the river scene near the end said very little which could not have been said earlier.
I would definitely like to see a “Director’s Cut” of this film which is considerably shorter!
