Hmmmmm.......Obscure Sci Fi Films:
The PBS Broadcast 1980 version of "Lathe of Heaven" It looks pretty cheap in some ways (laughably so in some parts) but you get what they were trying to do, It's excellently acted overall though. and the story is pretty damn good, I recommend this one, (You need to be in the mind for a slow burn, high concept type film with little action) Based on a book of the same name by Ursula K Le Guin, I recommend watching this at least once, DVD is expensive now (Long out of print), but it is on YouTube as of this writing.
1999's "Supernova" while not the best script is a visual guilty pleasure and I really like the concept the film is based on.
1980's animated film "Starchaser: The Legend of Orin" some interesting Rotoscoping/early cgi animation, a borderline shameless Star Wars rip off but a fun one! I recently rewatched this and while there were a couple of cringe parts it was still surprisingly decent.
1984 film "Explorers" plot is decent for what it is, pretty good score in parts by Goldsmith, I think this one's obscure by now, loved it as a Lad, and still as an Adult, it takes me back every time I watch it, I swear I can almost feel my M.A.S.K. toy's sitiing next to me on the living room floor as a kid whenever it's on.
1970's film called "Silent Running" Soundtrack is a little cheesy now, and some would say it's a bunch of 70's "Hippy-Dippy B.S." and maybe it is, but the arch the main character goes through is worth the watch.
1984 film "2010: the year we make contact" I'm not sure if this is obscure, maybe more like buried, I know even as a kid this film bombed when it came out, I personally actually liked it (Quite a bit, even as a kid, it was a more accessible visit to the 2001 universe.) Has some heavy hitters in the cast (Helen Mirren, John Lithgow, Roy Scheider) a pretty creepy synth score, and some of the shot's of Juptier are still achingly beautiful, I think this one is more accepted now among cult fans.
Supernova's the James Spader/Angela Bassett one isn't it? I remember getting it from woolies on dvd years back.
Silent Running was also a regular and I enjoyed 2010
