My wife's first D&D game was ... bad. I don't think it was really her fault, though.
She was joining a campaign already in progress with a DM who had *fantastic* behind-the-scenes stories going on (when you could puzzle them out) but who was a bit weaker at the table.
In the current game, we're traveling down a river, wondering when we're going to get introduced to my wife's character. We happen upon a lizardman encampment and proceed to have a knock-down, drag-out battle. Still no sign of my wife's character. We find out that a resupply shipment is due in a couple days, so we camp. Soon, the boats arrive and we ambush the lizardman convoy.
This fight takes forever, with lots of lizardmen swimming off, being tracked down, slowed-movement due to the depth of the water, etc. Finally, at the end of the battle, we find someone tied up in one of the boats: my wife's character.
Her first D&D experience involved several hours of not playing because the DM couldn't think of a way to get her into the action earlier.
This is the same DM who, when introducing two newbies to the game, gave one of them a Rogue (with Combat Expertise and a BAB of +0) and the other a ... druid?
