'Breaking Bad' Finale Aaron Paul Kills It at Cemetery Party

No spoiler alert required -- Aaron Paul's "Breaking Bad" finale party at the Hollywood Forever Cemetery was totally badass ... complete with blue meth (candy), and the most famous meth kitchen on wheels.

Aaron hosted the huge screening party at the cemetery ... where thousands of 'BB' fanatics showed up hours before the finale -- some in hazmat suits and Heisenberg fedoras.

Cast members ... including Aaron and Bryan Cranston spoke before and after the screening -- and the show's iconic RV also posted up at the party.

By the way, Aaron put together a last minute scavenger hunt around L.A. on Sunday ... giving away 20 more seats to the charity event.

How awesome is this guy? We're gonna miss you, bitch.
