Not really. Not directly.
The parents are such a nonentity in the comics. Only twice I know of in 50+ years of Spidey comics have they been relevant. Once in a Stan Lee story where Peter found out the Red Skull framed them as traitors before they died and he cleared their name.
The second time was in the 90's when Goblin and Chameleon built life like robots of his parents to fool him into thinking they were alive (yes it's as bad as it sounds lol).
Hmm, I'm not sure
why Webb went the parents arc, I mean, its not too bad a concept in principle, but it ended up taking up a lot of screentime from other characters. To put it into perspective, I'm almost 100% Richard Parker ended up getting more screentime than Ben Parker. I'm basically repeating what you've been saying for months, but you really can't do that. I don't have a problem fundamentally with Peter's Parents, but the weight they have on Peter seems a little, un-Spider-Man like.
I think the problem the reboot series faces is we got pretty authentic characterisations in the Raimi series. I mean, most are close to comic accurate, or at least try to maintain the essence of the character.
I think, in Webb's attempt to differentiate the reboot from the Raimi series, he's decided to change the characters a bit, which is fine, but he's gone too far sometimes and lost the essence of some of the characters. (The Osborns, for example) I think that's probably more erroneous than just copying Raimi's characters. Its not that the ASM series characters are BAD persay, they're just not as Spider-Many as Raimi's, at points at least. Some TASM characers I'd say are better than Raimi's, namely Gwen, Dr Connors as well. Even Spider-Man feels more natural in the ASM series.
As a whole, the parents were an out, as they allowed Webb to basically do anything he wanted with them, as you said, they're a non entity in the comics. That'd be fine if the buildup lead to something greater.
The problem is the reason the comics focus on particular characters more than others is those characters shape Peter. You lose that if you focus on insignificant characters, as they cut away the time Peter can grow with more important people. Say, Uncle Ben or even Norman Osborn.
ASM is fine as a movie, and even as a spider-man movie, but it loses out on the supporting characters sans Gwen and Aunt may, which is a huge shame really, but kind of unavoidable due to the nature of the remakes.
Given the negative reaction to that deleted scene in TASM 2, I'd say no.
I know I thought it was odd, but at least it was some conclusion. Better than deus ex calculator at least.
Not often a two film subplot concludes and leaves audiences asking why the heck it was even in there. Odd times for sure.
Worst part is the ship has sailed for a lot of these problems. Going to be hard to pull things back if that's what they're going for!
