I was entertained by Venom being brought into the MCU at the end of his movie, then being booted out at the end of the MCU movie. Guess that puts that debate to bed.
I was also thoroughly surprised by the gasps of shock in the audience when the other Spider-Mans showed up. Maybe I'm just on the internet too much, but that seemed inevitable when all the villains from the other Spider-Man movies showed up. But my audience flipped out when Tobey showed up. Sure it was cool, and kinda funny considering the rumors this whole time, but ... I mean, it wasn't that surprising.
