This film is a real dissapointment.  Harrison Ford gives a credible performance as the President and Gary Oldman pulls off his villain role with panache.  But this movie simply doesn't work.  Overall the film is completely illogical and frankly a bit too patriotic, especially for someone who comes from Europe.  Maybe logic isn't exactly what people are looking for when they watch a "no-brainer", but this film is really too much.
