I've found choice on demand good for documentaries and some sit coms that don't particularly follow an in depth storyline.

But for dramas I would not bother as if it doesn't start at s1 when I find it then it will probably ruin my viewing experience of the show should I get into it. Even if it did start at s1 I probably would avoid it anyway as I wouldn't want to get into a show and then not know when/if I can watch it again for s2 onwards
