It is supposed to take into account all sorts of factors like "down and distance". the score of the game, the amount of time left in the game, how much pressure the QB is under, and all sorts of other stuff. But until ESPN releases the formula it can not really be considered very credible. For example. . .
controversy erupted when the Total QBR system gave the Denver Broncos' Tim Tebow a higher rating than the Green Bay Packers' Aaron Rodgers in their respective Week 5 contests in 2011. Noting that Rodgers completed 26 of 39 passes for 396 yards and two touchdowns in a win over the Atlanta Falcons, while Tebow completed four of 10 passes for 79 yards and a touchdown, and six rushes for 38 yards and a touchdown, in a loss to the San Diego Chargers,
I believe they've changed the QBR system since that controversy though.
With that said, it's still partially opinion from what I'm aware of. It's like PFF grading, it means as much as you're willing to put into their opinions.
You usually don't see many great QBs with low QBR at the end of a season, but I wouldn't take the exact number to heart. A guy that ranks dead last in QBR probably didn't have a good season, but he's probably not exactly as good as the QBR number.
