This person on cricinfo makes a very good point:

I always felt that we batted for too long and should've declared, at the very latest, at tea yesterday. No way would England have attempted to plough down 290 odd or so (which would've been the highest 4th innings chase at Old Trafford), as all they need is a draw to retain the Ashes. I said in a previous post that we need as many overs as possible to bowl them out, and this may have been the final straw. We needed to take some big risks yesterday in order to win this match (which meant the possibility of England chasing down the total chasing a smaller target off more allocated overs), and our decision to not treat that 2nd session like a T20 match and score as quickly as possible has now given England the easy way out to take the draw and the urn.
This decision was nearly as brain-dead as the one we took at The Oval in 2005 when we walked off due to bad light when we had to win that test to retain the Ashes. I can understand that mentality if we were playing someone like Bangladesh or Zimbabwe, but when you must win a game you need to be out there for as long as you can, even if it means playing in the rain (which did happen back in an ODI back in the '70s)。 LOL to those who said the weather doesn't matter and you never play to the predicted weather forecasts. Days earlier, it had been known that the weather wasn't looking promising for days 4-5 of this test.
