First one was the best, back when full of hope and possibility, there were some OK moments, Chuck was a total buzzkill, overall just kind of fell off, like an abridged version of a better story, that just couldn't get there. More interested in romance (never been their forte) but too much sexual deviant dialog you'd expect between a client and a professional, felt rigid and too matter of factly, too blunt. After all this time too, still struggles with scale and proportions in scenes.
Don't get wrong, I enjoyed them for what they are, and I assume whatever is next will be even better. Cheers~
