Do you start a series knowing it ends on a cliffhanger or is canceled after 1-2 seasons?

I was debating watching Terminator Sarah Conners Chronicles for the first time. Looked it up and while it seems people like it, the fact that it ended early definitely gave me pause.

Feel like this is a more common thing with everything available on streaming now, including old and new shows.

What are your guys thoughts on starting a show knowing it will end cancelled and unresolved?
