that's true, but one might argue that the underwhelming ticket sells of TASM2 aren't likely so much this film's fault as it is probably the first film's, regardless of whether this film would be considered good or bad artistically. Batman Begins is a testament to the importance of the opening investment to a franchise, it didn't do well because of prejudice against the concept, but it was a really good plus entertaining film thus a sequel was worth green lighting because there would be more audience next time. WB is smart like that (don't know if Sony would've green lighted a sequel for BB with the profits it got or if they would've scrapped that and gone for something like Superman & Batman straight out of the gate)
Sony was ignorant to the importance of delivering in TASM because subconsciously and with some consciously, they (producers) still thought this as just the 4th Spider-man project, they didn't fully get that this was their new opening bid and how important it was. I enjoyed TASM for what it is, but it is admittedly a screw up, especially as the opening bid
and it's probably obvious to everyone that TASM2 is a much more viable film for the mainstream market in all it's colorfulness, humor and over the top action. But half of the masses were very much burned by TASM1, and had TASM1 being a similar film to this in the first place, the film and it's sequel would've made a lot more money
so my main point is, even if TASM2 in the eyes of the majority of the audience was on the level of Batman Begins or even TDK, it still would've made very close to the amount of what it has made now. it would've underperformed regardless of the artistic quality because of the damage TASM1 caused
