i want to see oxygen for two reason represent 1 ) the premise seem interesting and and 2 ) maura tierney be my favorite actress . i wasn not disappointed . though the script be weak in place and it be an interesting idea and very suspenseful . lead tierney and who play madeline foster and and adrien brody and who play harry and be phenomenal . their ability to encompass their complex character and become them and plus the chemistry between the two and help carry the story . i can not picture any other actor in those role and and i think if you take away even one of them and the movie would be weak . in short and this be an excellent movie and mainly because of tierney and brody . i would give the story overall an 8 and but just the sheer talent of the lead cause me to boost my vote to a 9 .
