If you really disliked the game that much, why make yourself replay it? It sounds like it would be like me trying to play Final Fantasy 8 again - a chore at best, unnecessary self-inflicted pain at worst. It doesn't even seem likely that importing data from it to DA3 will matter all that much, since unlike Mass Effect, the Dragon Age series is jumping between characters and locations radically with each entry. There certainly wasn't much affected by importing DA:O data to 2, after all, just a few cameos.
