I was too young to play it when it released and then I think I rented it right on the ass end of when Blockbuster was purging N64 and PS1 games and retiring them to the "for-sale" racks near the front. Definitely didn't like it at all, but I was still relatively young and maybe didn't get the jokes, but then again, I think I was maybe 10 or 11 at the time and definitely was getting into South Park so who knows. A bit blurry.
I mainly remember dark cave-like levels and it just didn't do anything for me. Especially since N64 already had two Banjo games, DK 64, and Mario 64. I always was super into A Bug's Life, Spyro, Croc, Rayman, Crash on PS1. There was enough to go round without Conker.
So no hard feelings towards it but just not a franchise I care much about.
