Yup. Kind of amazing what you can do with decent stories. Blake's 7 and 70s Doctor Who were notorious for cheezy effects, sets, props and costumes. But the stories really were pretty decent. Blake's 7 eventually annoyed me by how slow it progressed, but if you relax and accept that it's slower than your typical trek episode, it's perfectly fine.

The same era saw Survivors, The Tripods and Children of the Stones. Cheezy effects but very decent stories and still worth watching.
