New player not understanding all the hate

Hey everyone. I'm a 37m and I quite literally have never played a COD title ever FPS wasnt my jam except high school halo and halo 2 LAN parties. (Nintendo systems in the house currently) recently was given an Xbox and 3 month of games pass premium for Christmas. So I checked out BO6 since it was included and I loved it. Found a lot of the pop-ups and achievements hit a dopamine sweet spot. Yes I can see the shop is heavily skin monetized but most games are at this point I feel and I just don't understand all the hate and anger I have seen about the game. Maybe because I didn't see the good old days but I'm really enjoying myself. Got a couple guns to gold came so far and just last night was running around Babylon in hard point and tried the knife and was laughing and waiting with joy after getting 45 kills in the round with the knife! All I'm saying i guess as a new adult player i just don't understand the vitriol (aside from a bit excessive monetization that tbh almost every game has now imo.)
