Nothing Hitler about that. I know plenty of people who don't think much of Cowboy Bebop. The funny thing is, Cowboy Bebop is not considered a particularly stand-out anime in Japan. In fact, it is only really popular in the west, which means it completely missed its intended audience. I'll bet you that if you went up to Japanese anime fans and asked them what they thought about Cowboy Bebop, a good percentile of them would probably not even know what it is.
The reason it is popular in the west is most likely because it was aired in a manageable timeslot on TV, had a good dub and wasn't as "Japanese" as many anime are. Cowboy Bebop has many western influences and for that reason it becomes a lot easier for people in the west to watch and enjoy it. Hell, Shinichiro himself is basically a massive Westaboo and spent time of his life travelling the US. That is also why it is considered a good "gate-way" anime (A good anime to begin with if you want to get into the medium) for westerners.
Personally, I just enjoy the all-encompassing feeling the show has. It manages to touch on a lot of themes and morals in a short time and to me, that made the episodic nature of it really interesting. Quite a few references to western media in there too, which is neat. Not to mention that Spike Spiegel has the cool-factor. The soundtrack is also excellent and I personally got pretty emotionally invested in the characters of the show, which made the ending even more powerful to me. I am pretty biased though, as Cowboy Bebop was the anime I decided to tabula rasa my entire perception of anime with and give it an honest try without just immediately dismissing it as stupid crap. It really impressed me at the time.
I will say though, that I think that saying "nothing ever really happens in it" is a bit of an understatement. It's very episodic, but not without a story and progression.
