This film is probably the worst Spider-man film I've ever seen.
The plot is all over the place that it's hard to follow. The CGI on Electro is really terrible. That was also a problem I had with the Lizard in TASM1.
It was mainly made to rush a cinematic universe, not to tell a story. It's like multiple movies at once. Way to many villains and subplots. This film was so crammed that Black Cat only made a cameo and Mary Jane Watson has been cut out of the movie entirely (to prepare for the sequel).
The things I did like:
Some of the action scenes are entertaining. The cast did an excellent job. Andrew Garfield is probably the funniest Spider-man, Change my mind.
Overall, this film is a mess, but there is some enjoyment out of it. I wish Mark Web could've had full control over the project, it probably could've been something special. He's a talented director.
Would I recommend it? No. To Spider-man fans probably, because Spider-man in the big screen, but it has been done much, much better before. I would just recommend Sam Ramis Spider-man 2.
To movie goers? It's a waste of time. There are way better films out there.
In conclusion, this movie is bad, but not complete trash. I would give it a 3.5/10.
