We saw Kes' future in "Before & After", it wasn't very interesting.
She never used or explored her abilities, she didn't do much of any extraordinary in life and didn't achieve anything she couldn't have on Ocampa.
Really?! Dead Janeway, dead Torres, a Doctor with hair, Neelix actually doing something outside of the Mess Hall and an unnerving amount of borderline inappropriate intermarrying with children and bridge officers?
There's practical half a season's worth of The O.C. material there
Unless you just mean Kes herself... in which case, it did look pretty humdrum.
