did you see the original Solaris movie? how was it? i mean how was the book.
this made me think of the movie stalker. did you read Roadside Picnic?
Yes, I saw the 1972 movie Solaris. I don’t have anything useful to say about it. In general, I don’t like the idea of treating a novel and the movie made from it as a single unit. There’s no real connection between the quality of one and the quality of the other. I haven’t read Roadside Picnic by Arkady and Boris Strugatsky yet, although I have it on my shelves. I don’t remember if I’ve seen Stalker or not.
And the sequel, Tracking, if you can find it. (Serialized; Never published as a book)
The ending of Tracking implies a third story, which is not written to my knowledge. 
Surprised that this thread has gone this far without mention of H. Beam Piper (Little Fuzzy and a number of others; First Cycle, found as a manuscript and finalized and published posthumously) and Tom Godwin (Space Prison/The Survivors, and the short story The Cold Equations, both of which are in the eponymous collection recently published.)
One can make a reasonable argument that Scooby-Doo was (probably unconsciously) patterned after the Altairans in some of Godwin’s short stories.
Stalker was impressive. Gripping and compelling but not loud or harsh.
What a cool piece of trivia
No no no, gotta stop you there. The first couple of books were great, and then the slide started. If you really mean the first book or two, then I’m with you, but the series as a whole only rates 1 Donkey Ball.
Robert Silverberg’s Dying Inside.
Here’s a really obscure one that I think is worthwhile:
Forests of the Night, by Marti Steussy
Humans colonizing a planet bump up against creatures that physically resemble Siberian tigers, with feathers instead of fur. The scout team thinks they’re intelligent, but they don’t use fire, or have possessions, or even live in fixed locations, so the colonists think they are animals and want to kill them for their pelts, as an export.
Bad Idea.
[Spoiler]The main character takes off into the woods with a tiger she has developed a rapport with and gradually learns their culture and language and is able to prove their intelligence.
They have a purely intellectual “economy” where you have a “small-name” for everyday use, and a “big-name” that’s more like a Norse saga, and your status is determined by what you’ve seen and done, and how well you can tell about it.
[/spoiler]
Or you could just wait for the movie to come out.

Well, yes . . . and no. I agree that the series goes downhill. I don’t think it goes downhill as fast you think it does. I think that the overall idea of the series is so good that it makes up for the fact that it isn’t entirely well executed.
I’m 62 and it seems like I have been waiting half my life for that movie. I hope to make it to 90, so I haven’t lost hope yet…guess I’ll have to settle for “The Martian” later this year.
Someone above mentioned the Baen Free Library; it’s not quite as large as it used to be, but it’s still there. My two recommendations would be Eric Flint’s ‘1632’ and David Weber’s “On Basilisk Station” and “The Honor of the Queen”. Be warned, they are the starting points for very long series, but they can be read as a stand-alone book to.
Not at the literary levels of some of the above, but if you want to get lost in a good tale well-told…IMHO as always. And you can beat the price.
