In the movie Passengers (2016), it is demonstrated that 2 sensible adults, with proper authorization and even without proper formal training, can do quite a bit of ship maintenance.
Then, why shouldn't 2 crew members stay awake at all time? For example, suppose 2 crew members stay awake for 1 month (with natural sleep allowed of course), then they hibernate, and another pair stay awake, and so on until they rotate through the whole crew. There are 258 crew members so it would take 21.5 years to go full circle and, with the journey taking 120 years, each crew member will lose (i.e. age) by less than just 6 months.
This design, or some variant of it, would be far more reasonable that the one in the movie, which clearly demonstrates that the automated system is incapable of handling many unexpected events. Jim, for example, would be able to receive help instantly if he were still going to be awaken like in the movie.
Does the movie or its crew address this possibility?
