Wouldn't say it was terrible but man there was too much stuff going on. Did Rhino need to be in there? Electro was evil just because he got powers, Spiderman not remembering his name made him snap? The Goblin stuff was rushed.
Gwen dying was a sick scene(semi-accurate to the comics) but to be honest I didn't really care about them together for real. Honestly, I kind of got sick of the scenes with them just...talking. They had good chemistry though.
The presence of Harry as Peter's friend should have been somewhere in the 1st movie, to give us some...reason to care about Harry/Green Goblin other than saying he's gonna die unless he gets Spiderman's blood. Breh we were just introduced to you.
Overall?
I didn't hate it, didn't love it. It was enjoyable, there's better stuff out there though.
