It was indicated in a later internal flashback by Psylocke that Doug wasn't quite as ready for an adult relationship as he seemed. However, I agree about the pointlessness of his death.
Bad aging on certain characters. Even using Marvel time, Julie Power should not be in college, and Jack Russell's sister Lisa should not be the mother of an 18-year old young woman. They go on and on about how certain things make Spidey too old. Well, I'd say a super-kid he met as a pre-teen *after* his marriage now attending college ages him and the FF. So if Julie's in college, say about 20, why is Franklin, only one year younger than her sister who was perhaps five years her junior at most, still only 7?
And I will add Spidey's OMD/BND not merely for the stories themselves, but for the hell-bent nature of the Quesadars 'WE ARRRRRE GOING TO DO THIS'. You have a feeling the current staff served on Red Squad?
