Rambo Ridiculousness Scale
Rambo Ridiculousness Scale: the R.R.S. is based on the progressively preposterous nature of the Rambo series, the score is attributed (if the film is in fact worthy) in correspondence to the level of ridiculousness it shares with the Rambo movie (score from 1-4), and its inability of the film to inspire belief through the improbability of the events taking place on screen.
I did end up watching "the day after tomorrow" and I can now safely say it rates a 2 on the rambo ridiculousness scale, if not a low 3...
