Mr. DuLac’s review published on Letterboxd:
Space Hippie, Bruce Dern, tries to save a forest... in space! OK, the movie isn't that goofy, but I found that the story was weak. For example the 3 other human characters are barely one dimensional, and the story could have been fleshed out a lot more. The good however is that Dern is perfect in his role, the 3 robots are charming and the movie is extremely well made. Douglas Trumbull worked on the special effects for 2001: A Space Odyssey and it clearly shows... but it's nowhere near the same league. Happy I watched it though.
