It does make more sense once you've seen the all the episodes, but it can be hard to follow with the different time lines.
As for whether the second season is liked or not; I suppose it depends whether the viewer likes watching things with intentionally disjointed story telling. It's certainly more marmite than the first season.
Friend of mine's work colleagues gave up on the second season because it was so different to the first, and for them at least, not in a good way. I liked it, but if you don't pay close attention to what is going on I can see that it could be viewed as being complicated for it's own good.
I'm probably more eager to see what comes next though, because it became more than a show about a western themed park where people could live out their fantasies where the robots rebelled. Not really sure where the show could have gone beyond the first season, had it carried on in the same vein.
