Voyager would have been a fantastic series if it wasn't Star Trek. The Year of Hell showed what it could be. Taking dark and difficult decisions, fighting hard, taking casualties and huge losses. What made Voyager weak was that the captain always acted to find the peaceful, but often slower, way and that a ship in its situation should have been beat-up, scarred, war-torn veteran remembering the dead, peopled with a fair percentage of crippled (I assume they can't regrow a leg), and increasingly hard-headed, bitter and viewing new aliens in that light, i.e. as potential useful sources of supply.
