The preferred Twitter hashtag for "Breaking Bad" on Sunday night was "#goodbyebreakingbad." In case anyone hadn't already heard, the show -- which in six years progressed from cult favorite to beloved pillar of the pop cultural firmament -- was airing its final episode. Fans, of course, tweeted their goodbyes in droves.

The final act of high school chemistry teacher Walter White's transformation from good guy dad to dreaded drug kingpin was tense but cathartic episode, ending with -- spoiler alert -- White (played by Bryan Cranston) lying dead on the floor of a meth lab as the cops swarmed his body. All while Badfinger's "Baby Blue" played on the soundtrack. Perfect ending? A lot of fans thought so.

Cranston's acting colleague Rich Sommer, who plays Harry Crane on the AMC series "Mad Men," which is also about to end its run, wrote, "Sigh. That was a good time."

Colin Hanks, who once appeared on "Mad Men" as a priest, wrote, "Watched the Breaking Bad finale twice last night. Got closure, while at the same time felt sad for the path of destruction left behind."

Yvette Nicole Brown, star of the considerably less violent "Communty" on NBC, took note of one of the show's unanswered questions: What happened to Walter's meth drug fortune? Jack, the white supremecist drug dealer who took over Walter's empire when he went into hiding, offered to tell him in exchange for his life, but Walter shot him anyway. As Brown wrote, "One thing is abundantly clear...he could care less where the money is. Hilarious!"

Conservative author Ann Coulter found a way to always stay on message with her politics when she wrote, "#BreakingBad shows the importance of having a gun in the home." (In reference to Walter's invasion of the home of his former colleagues Gretchen and Elliott Schwartz.) Nonetheless, she went on to praise the finale, writing, "FANTASTIC #BreakingBadFinale! Thank you, Vince Gilligan! Much better than anyone imagined."

Coulter's political opposite, Rosie O'Donnell wished that the cast could feel the joy that stage actors felt, writing, "u know when u see a great movie and the crowd claps - or on b way when u stand up - i wish the #BreakingBad cast n crew could feel that now."

Blink-182 bassist Mark Hoppus was inspired by Walter White's small-businessman work ethic, writing, "If you're sad Breaking Bad is over I will hold you close while you cry and stroke your hair and whisper "Shh, it'll be okay." 5£/$7.50 per."

Prolific author Joyce Carol Oates write this headscratcher of a reaction, "Ellipses in final episode of 'Breaking Bad'--contemporary filmmaking that takes for granted considerable visual memory in viewer."

"Bridesmaids" director Paul Feig wrote, "Aaaaaaaaaand ... here come the waves of depression as I realize there will never be another new episode of Breaking Bad."

And "Black Swan" director Darren Aronofsky said farewell, writing, "almost like losing a good friend. congrats to @BreakingBad_AMC a historic run."

Even billionaire investor Warren Buffett got in on the "Breaking Bad" finale hooplah, tweeting this picture of himself auditioning as a "Walt successor."
