"Perfect Stranger" is quite thrilling but the finale simply absurd, moronic. It doesn't lack thrills and pshycology, being it a phsycological thriller. Played intensely, with moments of entertainment not delicious but decent though, everything's spoiled by the foolish and outrageous ending - the mystery resolution is too convoluted. It looks like a pre-packedged thriller, "homogenized" I'd say, with much part of it taking place in chats. Bruce Willis and Halle Berry have acted much better in past, but are watchable regardless, as well as Giovanni Ribisi; suspense thriller is made bearable but eventually degenerates..
