Oh I mean it's ok for the DOFP storyline (any time travel stories really) where it helps the story and is the only way of doing it but I'm more referring to Cyclops X3 type deaths with characters set in the present. If the character (even a minor character) is worthy of having their death mentioned at all then something should be done onscreen to get whatever emotion is possible from the situation. If an actor is unavailable then of course it would be forced in that instance and they wouldn't have a choice but to take an inferior course of action.
