I will never forgive Lenkov for the #h50 finale. Self-serving favoritism. He cast a shadow on the whole series legacy in the finale by shoehorning his ooc retcon fantasy above the input and ideas of his co-director and main star. Toxic indeed. What a shame.

about peter lenkov too late. He ruined h50 maybe bring it back at lease to redo the ending.

@Banshi131
Here’s hoping that @CBSTVStudios will offer a small episode arc (if cast is willing) to wrap things up as they SHOULD have been, not in the clearly vindictive way Lenkov did. Most #H50 fans KNEW that final episode was so off base, & now we know why.

@HenryScarf
Good riddance goodbye Peter Lenkov and all of us fans of #McDanno and #ScottCaan of @HawaiiFive0CBS20think you got what’s coming!!! Too bad you ruined the final season!!
