Part of loving the show is acknowledging and forgiving its flaws, so when Ian and Barbara leave, you feel it. So that when Steven goes back for his stuffed panda, you can chuckle. Groan at the Mary Celeste sequence so you've paid your dues for the Dalek/Mechonoid battle sequence. Roll your eyes at the Aridians, the Mire Beasts, and Ian's cardigan trap, so you're watching with integrity when the Doctor shows his heroic character in the face of the Dalek ultimatum.
Terry Nation has a lot to answer for, but he's undeniably an integral part of DW's rich tapestry.
