i guess you can say that los has more scope and daring ideas, but it just brings out the flaws more when they're so underdeveloped. and when you have a slew of ideas that are underdeveloped, i feel that really hurts the story more than just a very minimal story that's bad. it's more like less and crap, or more and crap.
It's an absolutely respectable opinion, and I couldn't or wouldn't want to change it.
I personally feel LoS' story had 3 main advantages over what we usually get:
1) delivery. Seriously, the entire history of CV is made of two characters facing off on a still screen exchanging lines of text before facing off. In LoS we had stuff like Carmilla's death, the entirety of chapter IV, Laura, ch 11... it comes to life before your eyes. Yes, epic for the sake of epic isn't anything we should absolutely strive for, but to me it was completely welcome to see my favourite series get some of the best action set pieces in the industry, and dialogue delivered by top notch actors.
2) it did gothic good after so many questionable games. I still think OoE nailed the right atmosphere in a way that is closer to CV's heart, but still I absolutely loved the aesthetics of the game. The crypts, the butcher, basically every chapter after IV... that's how CV should look like in 3d.
3) and as I said before, it sparked some life in the series. Prolly because it's a reboot, and that was inevitable, but I like sitting here and thinking "where will the story go next?".
Would I have preferred to do so in the MAIN canon of the series? In a continuity with the old mythos? Hell yes. But IGA happened, AoS happened and I can finally be excited for something new instead of being stuck complaining about "main" games that some other people legitimately appreciate, and simply annoying them to no end. Between you and me, I'm probably the one who is more sour. You didn't like LoS, but that's one game and all hints point at the fact that the "main" storyline will keep moving in IGA's hands - so you're likely to get more of what you like. I've been stuck with disliking much of the last CV games for years now, and now my favourite title in years is a sidestep game that doesn't feature a lot of the characteristics that make me love CV.
