Can't we use spoilertags in these comments?

Let's try.

I can forgive the ending because of the forced censorship in practice at the time, but some of the stupid decisions made by the main characters (especially when one of them is a professor of psychology) prevented me from buying a lot of what takes place. Aside from that, it's a decent suspense flick.

The ending is very cheesy (although maybe less so in 1944 -- we've certainly outgrown that plot device in the last sixty-plus years). Other than that, brilliant thriller.
