Staggeringly, unmitigably awful.
Traditional science fiction used to present the notion that humanity would carefully select only its very best for that initial encounter with an alien civilization. Recent stories have left the selection up to chance, (Arthur C. Clarke's "Rama" sequels actually postulated a sampling of people dominated by criminals.) but "Iris" leaves first contact up to the most pathetic assortment of head cases, psychos, deviants, perverts, sadists, masochists, schizophrenics, co-dependents, and just plain neurotics that Earth (and the Moon!) could rustle up!
This shipload of losers rockets off into space, seeking to...
find themselves...
or find out who they are...
or gather their feelings...
or learn how to relate...
or heal...
or grieve...
or get in touch with their inner beingness and personism...
or some such nonsense!
No kidding. Every plot twist comes in a blizzard of "issues," and is followed by a period when the characters decide "to move on!"
Here they are, orbiting a hostile rogue planet on the outskirts of the solar system, and en masse they plunge into a computerized virtual reality world to escape from, well, real reality!
The very first few disgusting lines of the very first page of the first chapter are a valuable flag for the unmitigable avalanche of literary sewage to come.
One woman actually freezes to death because her shipmates are too busy with life and death survival concerns to rescue her, as she expects them to, from her own narcissistic stunt out on the subzero surface of an airless asteroid.
Whew! Fortunately, the only aliens they all find are a long dormant shipload of resentful biomechanoids, rebellious robots and ambiguously unfriendly computer programs.
With ambassadors like this to the cosmos, the human race would be lucky not to get blown to oblivion just so the universe could be rid of our whining!
Be sure to miss this one!
