Right from the very first swing, I was hooked on this - it's a fantastic, fun, action packed romp with a brilliant story, memorable characters and PLENTY of things to do to keep your attention. Plot-wise, this is as good as any Marvel film and I actually preferred it to the Spider-man films in the MCU. I didn't expect to enjoy the sections with Peter Parker as much as I enjoying webbing around the city, but they don't just act as a sensible respite from the fighting, they really do compliment action sequences perfectly. The mini puzzle games found in the lab Peter works in are clever and thankfully aren't OTT in volume or difficulty.
I was a bit concerned that the stealth sections had been dumbed down too much early on, but after unlocking some more gadgets and getting used to the feel of the controls, those sections became far more satisfying. I still think the Batman Arkham series has the upper hand when it comes to stealth, but Spider-man beats it in every other department IMO.
There aren't too many niggles I can think of - maybe the annoying jet pack bad guys who really pissed me off on occasions, and 'JJJ's' radio shows are a fucking ballache to endure (you can turn these off though) but the downsides to this really are few and far between, vastly outweighed by the sheer joy of exploring NYC and showing off the numerous Spidey skills.
My favourite game on the PS4, my first ever Platinum trophy and an absolute treat of an experience.
