I agree that I wish the DLC was one whole package. I didn't like how the 3 were separate but wouldn't label it bad.
Maybe for the next game they'll just have a big expansion instead of smaller DLC. The worst part about it was the costumes didn't do anything, I didn't use all the costume powers a ton but it was sool.
I didn't mind that about the later costumes lacking powers, I mean we got so many free costumes and look at what a lot of these lesser games are charging for different costumes. I felt the love from the developers with the amount of costumes, with some like Future Foundation releasing long after they had any reason to continue to do so.
I do agree that no matter what the DLC shouldn't have been split up, even if just for the perception of it. It also came out too soon after the game, which led to a lot of people saying "Durr well why wasn't that in the game." So, I think just for perception reasons the DLC shouldn't have come out until at least several months later, and it should have been one package.
That's not to say you can't have separate DLCs, if you notice no one's complaining about the Witcher 3's Blood & Wine and Hearts of Stone, it's just that a DLC the length of the Spidey one comes off better when played as one cohesive package, thus you wouldn't have so many spreading the false narrative that the Spidey DLC is "bad."
Literally the only thing that was questionable about the game was the handling of the DLC, but look at the bright side, only us Day Oners (and there were a lot of us) will remember that now as this Game of the Year edition effectively erases that problem for future webheads.
