I hate to judge after one viewing because there hasn't been a Spidey movie yet that I actually didn't LOVE after the first viewing. Even ASM2 and SM3, I thought were great when I saw them in theaters. But not a single one of them held up to repeat viewings.
So having only seen Homecoming once, I'll say it was easily the best Spidey movie yet just because the first five all ranged from "really bad" to "watchable". But I reserve the right to see it again and realize I actually hate it!
