On the contrary, 24 moves spread across 6 pokemon is part of what makes pokemon strategy deep. You can't indeed cover everything at once, so you have to know how to analyze the metagame and predict what the opposition will bring and how to best counter it while having some contigency plans.
Ray Rizzo for example won 3 world championships in a row. Why? Because he knew how to read the pokemon metagame better than anyone else, aways staying one step ahead of the competition.
As for pokemon "just fainting and coming back and magically brought back by high tech", that's no worse in any way from your typical RPG "
You tecnically can die but there's a million ways of bringing you back to life so death is worthless". There's little diference between fainting and dying when both can be solved with the same ease. If anything, death is usually easier to solve in most japanese RPGs out there, with auto-life and mass ressurection abilities and whatnot.
But you know what pokemon has? Cemeteries. Hundreds of pokemon graves lined up, with people visiting for griefing their losses. Haunted by ghosts of all kinds. Ever since first generation that the game recognizes that yes, pokemon eventually die (and there's also at least a pokedex entry of pidgeots eating magikarps).
And c'mon, just because there's a female providing a commercial service it automatically counts as sexual innuendo? Would you prefer if they were faceless automated machines?
As for "love and friendship", last time I checked pretty much every japanese RPG has that.
However that's not mutually exclusive with "meticulous training regimen", and I'm pretty sure 50% of the NPCs you meet in any pokemon game will be repeating some sort of "gotta train your pokemon more/harder". And you are in your way to conquer the pokemon league for fame and glory, stuffing your pokemon with bitter drugs they hate if needed.
Plus, your character is not a superhero, quite in the contrary. You're just a kid from the countryside, not the chosen one/last descendant of an ancient race/royal lineage blessed with exceptional powers or that hapened to trip into a super artifact of power.
Which is precisely part of the big appeal of the series. The player can identify quite well with the character (even if they're older).
