Doctor Who: Every NuWho Companion Ranked
10. Ryan Sinclair
There are two major issues with Ryan. The first is that he's just boring. I can't think of a single moment where he seemed to show any real form of emotion throughout his time on the TARDIS, but worst of all, and this is a problem with the entire 'Fam', he feels like a witness to the story, but never a driving force. He just seems to react to what's happening.
The second major issue is his portrayal, and more to blame, the writing's portrayal of his disability. Ryan suffers from dyspraxia, but only when the plot needs him to. You see the show doesn't do a very good job of showing just how bad dyspraxia can be, all we see about it from Ryan is that he can't ride a bike and he has trouble with ladders. This isn't a terrible issue but it's just kind of annoying that, for the most part, it seems like they forget about it unless it's relevant to the plot. Thankfully, they do show that Ryan is still suffering from it even after these adventures, showing you that there isn't an easy fix. But it just always felt convenient from a writing point of view.
