Just watched.... no way is Kingpin dead. That's just total "bait" to watch the Echo series to find out what happened.
Seems like either Kingpin somehow gained super-powers or this is just not the version from Netflix Daredevil but a totally different guy in a different universe.
Overall, some great action and great fun in this finale.... like a million tracksuit guys suddenly out of nowhere.... and like none of them had guns for whatever reason. Kazi brought their only sniper rifle I guess. I know they used that one arrow to magnetize stuff and take the guns away..... but like a thousand more guys came rushing in afterwards.... plus guns are long range weapons, just stay out of the range of the magnets, and shoot the people you have the high-ground on.
Pretty sweet to see the full Rogers: The Musical song (though it really does seem like an Avengers: The Musical)
