History YMMV / BlueCatBlues

* FanonDiscontinuity: Many fans like to pretend this short never happened due to the extremely depressing tone and DownerEnding, which are seen as very out-of-place in a {{Slapstick}} GagSeries like ''Tom and Jerry''.

* WhatDoYouMeanItsForKids: A large reason this short is so shocking to many is that it's a dark short featuring infidelity, {{Gold Digger}}s, and suicide. The short was intended for general audiences, not kids, but [[AudienceShift years of the franchise being pandered to kids]] has left modern viewers seeing it as exclusively for children.

* CommonKnowledge: The already-depressing "Blue Cat Blues" is often cited as the final original Creator/HannaBarbera short and thus the [[SeriesFinale finale of the series]] as a whole, given [[DownerEnding how the short ends]] with Tom and Jerry being {{driven to suicide}} by train. In actuality, there were several more original shorts produced afterwards, and the ''actual'' final ''Tom & Jerry'' short by Hanna Barbera's unit is "Tot Watchers," which ends with another DownerEnding with the titular duo being arrested, albeit PlayedForLaughs. (And anyway, it's not like death actually ''[[DeathIsCheap sticks]]'' in this series; an earlier short had Tom being ''executed by guillotine''.)

** Jerry's fruitless efforts trying to save Tom from pursuing that GoldDigger. Despite their never-ending feud together, the opening premise described the two of them as friends. But all of this led to both of their demises at the ending.
* ValuesDissonance: In the ending, as the train rumbles towards the duo, comical music starts playing and the usual MGM outro plays like normal, suggesting that this was supposed to be for comedy. Granted, SuicideAsComedy gags were common back then, but most modern-day viewers find the joke to be more sad and disturbing than anything.

** Don't give everything or sacrifice your well being in order to get a partner, especially when she/he is not paying attention to you. This is more evident when Tom signs a contract giving up two limbs and 20 years of slavery to get money in order to outbid Butch.
*** At the very least KnowWhenToFoldEm and always keep the receipts for the stuff you bought. Tom could have escaped his predicament if only he was able to return the rejected presents.

* NightmareFuel: Once that train hits our duo...well, [[NothingIsScarier we'd better not talk about it]]. And not in a cartoonish way, either. [[KeepCirculatingTheTapes No wonder this has rarely ever aired on television.]]

** Jerry’s girlfriend Toots. While most people believe that she dumped Jerry for another mouse because she was a GoldDigger like Tom’s girlfriend, since we didn’t even know that Jerry had a girlfriend until after we learned about Jerry’s failure to help Tom, it’s possible that Jerry’s desperate effort to get Tom to see the truth about Tom’s girlfriend caused Toots to believe that Jerry was neglecting her in favor of trying to save Tom, and such feelings of neglect caused her to turn to another mouse.

** Don't push away those who care about you by obsessing over someone who doesn't. The beginning of the episode's flashback makes it clear that, despite everything, the titular Tom and Jerry are close friends, but as soon as the white cat enters the picture, Tom begins throwing away everything else in his life just to have a ''chance'' at winning her heart. By the end of the episode, he's left with ''less'' than nothing, and even Jerry sadly acknowledges that there's nothing that even he can do to cheer his old pal up.

* SignatureScene: The final shot of the short, where Tom and Jerry are sitting on the train utterly heartbroken and depressed, waiting for the train to end their misery. It's gotten to the point that most viewers are more familiar with that closing image than the rest of the depressing short.

** Don't give everything or sacrifice your well being in order to get a partner, especially when she/he is not paying attention to you. This is more evident when Tom signs a contract giving up a leg and 20 years of slavery to get money in order to outbid Butch.
*** At the very least always keep the recipes and KnowWhenToFoldEm. Tom could have escaped his predicament if only he was able to return the rejected presents.

** Watch out for {{Gold Digger}}s. Ditch the parasites as soon as you find out no matter how pretty or charismatic they are. It's not worth it.

* FridgeHorror: Tom getting DrivenToSuicide because he fell for a GoldDigger female cat and drove himself into poverty in a failed effort to win her is terrible, but it only gets worse if you stop to think about the ridiculously rich Butch and what might happen if he ever lost his money or spent it all on his wife. She’d probably dump him for some other rich sucker who, and would Butch [[DrivenToSuicide follow in Tom’s footsteps?]]

* TearJerker: All of it. Tom and Jerry DidNotGetTheGirl, in long sequences for the former, and are shown to be ''very'' down in the dumps about it. And once they sit on the train track depressed, [[DrivenToSuicide the train comes not long after]].

She’d probably dump him for some sucker who was rich, and would Butch [[DrivenToSuicide follow in Tom’s footsteps?]]
