The Thin Red Line (Criterion) picture problem?

[filmmusic]

Hello.
I wanted to ask you if at around 29.20'', you see this quality of picture:

[Show spoiler]

Notice the two faces and the shadows!
It looks like really bad quality.
now, in the next shot which shows the colored person, the quality is great.
Is it like this in your Bluray disc too?

I watch the Bluray in my pc and I used 2 software:
TotalMedia Theatre 5, and MPC-HC.
That shot is the same bad quality in both.

i haven't seen the whole film, but as i got through it in places i didn't notice anything else except this particular shot which seemed bad to me..
