Should I use a streaming month I accidentally renewed just to make the charge feel worthwhile?

The subscription receipt arrived before breakfast: another month had started. I'd signed up for a trial to watch one filmed concert, then forgotten to cancel. I knew it would renew; I hadn't put the date anywhere I'd see it.

I went into the catalogue looking for enough films to justify the month. An hour later I had a list of things I didn't especially want to watch. My sister said I might as well get my money's worth now.

I haven't checked whether the service will consider a refund or completed the cancellation steps yet. Those are the practical jobs. But even if the charge stands, I don't want a forgotten trial choosing several evenings for me.

How do I separate dealing with the renewal from deciding what entertainment I actually want? It feels wasteful to leave the month unused, and equally wasteful to fill it with viewing I picked only because I'd already paid.
