I liked it. At the end where Mary Jane goes to Peter's house still wearing the wedding dress Peter realizes how stupid he was and they kiss. There was also an applause during that kiss from the viewers(including me)
Here is my "bad guy" guess for the next movie:
1. Jameson's son, the astronaut, brings "the symbiot" from space thus we have
Venom!
2. Dr Connors(spell correct?), who is Peter's teacher, tries to recover his missing arm thus becoming
The Lizzard.
3. Harry wants to take revenge thus becoming the new
Green Goblin just like in the comic.
Any of those three is nice though the Green Goblin option has the most chances of happening.
