Don't know what to say, I had a blast watching this episode. I was laughing at every interaction between the characters confronting the surrealness of it all.

It's 46 minutes of the team trying to prevent Gwen's wedding from going horribly, and, obviously, failing catastrophically.

Yes, this is not a profound or thought provoking episode, but that's the point. We just had 2 episodes of pure sadness and death, so this is just a great palate cleanser.

So yeah, I see I'm in a minority here, but I loved it, will rewatch when I want to just have fun and don't think too hard. This is what's great about Doctor Who, you can have tonally different episodes follow one another and it just works.
