I've seen the film yesterday since it is already released here in the Philippines, and I say that
1) The Lizard is an okay villain for this part. The film is a reboot so it starts again with the (re)introduction of Peter Parker and all that, so i think a villain with a pretty simple story and simpler powers (compared to mysterio, chameleon, etc). Dr. Curt Connors is also personally related to Peter Parker, in a way that Norman Osborn is related to Peter in Raimi's Spider-man 1, so it is more fluid to establish a connection along with the (re)introduction.
2) I would still prefer Spider-Man 1 (without 2 and 3) over the Amazing Spider-man 1. :)
