The Mysterio illusion bits were cool visually.
I lol'd at the one guy being the scientist who got yelled at by Obediah Stane in the first Iron Man ("WITH A BOX OF SCRAPS!"). Was it actually the same actor though? I need to rewatch that.
Pete and MJ were cute. Not quite as much as Pete and Gwen in the TASM movies though
And finally seeing Spidey swinging through Manhattan at the end was great! There wasn't really any of that yet in the MCU.
Gonna be interesting to see where they go with Spidey's secret identity not being secret anymore. Also being framed and such.
And uh.
*takes deep breath* THEY GOT JK SIMMONS BACK AS JJJ, WTF!!!!!
I had a stupid grin on my face at that part, so awesome they recognize you don't mess with perfection =P
And then the real Nick Fury chilling on a Skrull spaceship. I got a kick out of somebody yelling "Tahiti!" when they saw him at that beach. Agents of SHIELD fans unite! There are dozens of us!
