The Truth About Bézier Graphs

I am rebounding another time I trolled @Dribbble. Is it just me or or are these bézier line graphs that are becoming more and more frequent sacrificing what could probably be a better design decision for what's trendy and just darn sexy? Don't get me wrong, I too love a good hot bézier over a minimal grid. But, let's be honest. Béziers look best when the points have a good distance between them and you can get some decent distance on your handles. And, while I might be generalizing, line graphs and charts are meant to simplify and visualize change over some variable (in this case time). That change is rarely going to be perfectly positioned (and have few enough points) to result in these beautiful bézier curves. In use, bézier lines will sadly probably look like anything from a toddler drawing a line to a slightly smoother asymmetrical waveform.

I am not saying there's never a use, but am I crazy or is this a little out of hand?
