If forced to watch this movie, I strongly recommend you escape at the first opportunity.
Don't worry, there will be many, so your escape is assured. During every scene with Todd and Trumbo, they follow every badly delivered line with approximately ten seconds of staring blankly at the camera. "Line... what's my line? Cue cards! Cue cards!"
These times are your chance! While Claire stares blankly at the camera, or possibly chain-smokes through an entire pack of cigarettes in between lines ("Well, I like to... Um... Line...? *smokes an entire pack of cigarettes while Noel stands stiffly looking into space* Oh yeah, go to the, uh, bar, right..."), you will have ample time to make some lame excuse and escape.
Do not squander your opportunity! While the opportunities for escape in this film are limitless, every second you remain will simply increase your sleepiness, until after an hour you'll be permanently mired in a zombie-like state of half-sleep from which you may never recover.
This movie most closely resembled twelve hours of the Oxygen channel, only, more compact, and everyone speaks in a soft voice so as to not wake you up.
Despite its flaws, this movie is still better than such screen gems as xXx and Starship Troopers, so 2 stars.
