Bounty Hunter/YMMV

Complete Monster: Sure, Jango did his share of bad things, but Montross even planned on killing Vosa and taking her place as the new leader of the Bando Gora, a cult bent on brainwashing as many people as possible and conquering the galaxy.
Crowning Moment of Awesome: Jango manages to defeat Komari Vosa alone using only his pistols against her lightsabers.
Demonic Spiders: The nexu on Malastare. They're highly resilient, strong, masters of the Deadly Lunge and they're completely silent. The only way to slay them is to use the poison darts. Also, any enemy with an explosive weapon, or the Tusken Raiders' massiffs on Tatooine.
Game Breaker: The last level can be easily passed with the help of the flamethrower.
Goddamn Bats: Many enemies, especially snipers and artillery men.
High Octane Nightmare Fuel: The Bando Gora followers are quite scary. Must be their glowing red eyes or the fact that they barely look human at all.
Player Punch: Roz gets tortured and killed by Montross. Keeping this in mind, his ghastly demise is far more enjoyable.
Tear Jerker: Roz's posthumous message shows how much she really cared about Jango. Considering it comes from a Toydarian, a race known for greed and selfishness, this is quite surprising.
That One Boss: Komari Vosa.
That One Level: Starting from the second level on Oovo IV, all of them.
That One Sidequest: Collecting all the Secondary Bounties and all the Mandalorian Golden Feathers.
