So, my second viewing (on Blu-ray) only highlighted what I didn't like it the first go-around (and primarily afterwards as I thought more about it). The plot is non-existent, the villains are a complete waste, the lines are cheesy but not in a funny way and at 140-minutes, it does feel a bit too long, though not helped with additional characters. Then there's Harry. While I liked Dane DeHaan, that character should've just been introduced in this one and THEN become Spidey's archnemesis in the third, though I suppose they wanted to avoid the comparisons with Spider-Man 3... As it is, his character, and subsequent development (which is a whole other can of worms*), is rushed.
Now, I do admire the visual effects, costume designs (save for Electro's imprisoned part where he looked like Mr. Freeze) and although the character wasn't well written, Andrew Garfield wasn't bad and his scenes with Emma Stone were great.

* Why Peter was such a dick and didn't give him his blood still makes no sense. He's afraid it'd kill Harry? Well, Harry was already on his way, although he seemed to deteriorate, mentally, at a faster rate even before he took the venom.
