When you think about it, quite a few episodes from Season One had somewhat abrupt endings (namely My Three Suns). But the series developed as it went on, like any show does. Every season had a slightly different style to it.
The majoirty of Season One was to basically establish the premise, the setting, the characters and the future in general, and towards the end it began to parody waaaay too many movies. Season 2 was much more character-based, and probably the least science-fictiony of all the seasons. Although Season 3 did do a few shippy episodes, the majority of the season was very comedy-driven, with a few exceptions (such as Luck Of The Fryrish), and finally - Season 4, which was when the show began to fluxuate. Although a few episodes were just for comedic value, most were either very shippy or very science fictiony.
Season 4 is when the show became experimental, so it obviously didn't appeal to everyone. I wouldn't say that it was because the writers were running out of ideas, no - quite the contrary. Anyway, my point is that I personally think that every season has a different style to it, and you can either see that as a good thing or a bad thing. Either way, as many other posters to this topic have said - the show was cancelled just as it was maturing.
