I concur, although I was able to make it through the whole movie. Even the Captain America cameos were disappointing, as was their version of MJ--which seemed to me to be a bad emulation of Daria Morgendorfer, if anyone remembers that character. I suppose they felt the "va-va-voom" version of the character was inappropriate for a high schooler, but still. . .
The Spider-Man of the comics never needed a mentor. Nor did he need a Cadillac Spider-Suit with more gadgets than James Bond's Aston Martin. He got by just fine on his own, even with the press, the public, and every lawbreaker this side of The Red Skull against him--and that included The Red Skull on a couple of occasions. That was what was so disappointing about the MCU's Spider-Man, who's basically become a wholly owned subsidiary of Stark Enterprises.
I didn't bother with the second movie, either. I seriously doubt I'll bother with the third.
