Surely there was no funerall because the writers were leaving a doorway open for Cutter to come back.
Whatever they said about giving him an emphatic and definite ending we all know they mixed his death up with the clone storyline to make it ambiguous. They could then later reveal he had not really died and that his death was faked by Connor or Jenny or other team members etc.
(Perhaps thats why Jenny was smiling as she walked off in her final scene. She was going off to be with Nick who was in hiding!)
