[Locke]

I dunno, I think there is a limit. Using a slightly weird example on paper, the 2005 War of the Worlds was extremely contrived, where for all the wanton destruction by the aliens, Ray was able to survive every near miss and come out on top in every scenario. It was so ridiculous, that despite the awful things happening to him, he seemed so immortal that I found his near misses hard to care for.

Likewise for sentai, we know the heroes will always win, but what matters is how they win and the conflict they overcome to get there. I have had huge frustrations at the ineffectual nature of sentai villains, from the Messiah Metaroids who despite all their build up achieved absolutely nothing to the Zangyack who were depicted as a cruel, destructive force in flashbacks but the ones the Gokaiger actually fought were always largely comic relief, and so I found it hard to enjoy the battles as there was never a tangible sense of danger to quell my disbelief. I never questioned if they'd win, it was all too easy.
