Oh, you mean re: the direction of the shadows? Yeah, I didn't really feel it detracted from the quality of the ep...it just kind of bugged me, just because I'm pretty sure if they'd taken more care with the shadows they could have done it without having any of those problems, and because the shadows were drawn attention to so much at times in the episode and at other points they didn't seem to bother. (Also that's the kind of thing that kids watching would tend to notice, I think...they wouldn't notice monsters made of bubblewrap, but I know as a kid I would have been like "WAIT BUT THE DOCTOR SAID NOT TO LET YOUR SHADOWS CROSS, WHAT'RE YOU DOING D: D: D:"
