That said, there are still some redeeming factors. Piper and Saucerful are both way too psychedelic and weird for weird's sake, but you will come across a good song every now and then - I have always been enamoured by Astronomy Domine, Chapter 24, Remember a Day, Set the Controls... I think the main problem is the genre incompatibility. I mean, I don't know how much the Pink Floyd fans and the Jefferson Airplane fans overlap.
Ummagumma's shit, really. The live album has its merit, it's mostly good with a good performance of Astronomy and Eugene - a rarity that's really good enough to try out. But the studio work is just appalling. The only thing that even approaches being a song - Grantchester Meadows - is just way too long. I like some parts, there are parts of both "Sysyphus" and The Narrow Way I like, but was the album supposed to disappear tomorrow, I wouldn't shed a tear.
Atom Heart Mother is really an underrated album - I know the band themselves have said it's bad, but I really like the title track, I like Summer '68 and the whole atmosphere of the album's just pleasantly different. I think it would deserve more love. The Psychedelic Breakfast, however, spoils is. I think I wouldn't even mind it, were it not that overlong.
Meddle is very uneven - the first album in the "classic" sound of Floyd, it has a lot of good music (One of These Days, Fearless, Echoes), but also some experiments that should never leave the vaults (seriously, Seamus?)
And Obscured by Clouds is a forgotten classic. Every DSotM fan should give this one at least 3-4 listens ... it's criminally underrated.
(Yes, I have deliberately forgotten Soundtrack from the Film More - I have heard it more than once, but not more than five times and I don't remember it fondly. Will have to try it out again once more some time.)
I think the main problem is the fact that the people who'll aprreciate those early Syd experiments aren't your usual prog/art audience... and vice versa, fans of Wish You Were Here and Animals will have hard time listening to Scarecrow or Gnome.
And, of course, moving further in time, then there's the whole Waters/Gilmour can of worms. Are the albums after The Final Cut any good? Is TFC itself any good? I kind of understand both sides - I believe the Floydsters greatly benefited from the fact Waters had his vision and pushed the band in his direction - that way we got the conceptual DSOTM, WYWH, Animals and The Wall, all of which are very "Watersy" (at least from the lyrical point of view) and all of which are really hard to hate. Then, when Waters ran out of steam and started to not entertain and preach (as before), but only to preach (as on TFC), the band seemed burnt out. And Dave pushed the band into two more albums, out of which we got some really beautiful songs like Poles Apart, High Hopes or Learning to Fly. Though I admit that to swallow A New Machine (Pts. 1-2) or Keep Talking is too hard a task at times.
