All the protests are irrelevant. The show is gone now. It sucks on toast & all, but like it or not, it's always best to walk away leaving the audience wanting more. Leverage has definitely succeeded on that front & I may hate that it's gone, but I'd rather fondly remember it's wasted potential than pine for the "good 'ol days" before the show outlived its coolness.
Leverage was a blast & a half while it lasted. I'm simply glad I was there while it all happened.
