This one is pretty rough in certain regards, but I don't know if it fully deserves the infamous reputation it gets.

It isn't the best story in the world but it is made competently enough and I actually really like the "Day One" aspects of Day One. When we're dealing with Gwen getting to know Torchwood and the types of adventures ahead of her, all while she gets to know the team a bit more, I'm having fun. The sex gas stuff definitely comes across as Torchwood showing off how adult it can be in relation to Doctor Who, but I find it more underwhelming than anything else. I don't doubt that the subject matter doesn't come across as weird though, and sets the tone of the series in a rather unfortunate way.  Not a great episode overall but it does vaguely have its moments.
