They kind of are though. The Qui-Gon highlights:
- Identifies poisonous gas (by smelling it?) and responds by turning off lightsaber and holding breath, presumably hoping someone opens the door. (Fortunately the droids open the door.)
- Upon discovering an army set for invasion, he abandons the plan to confront the leaders who control that army in favour of warning the Naboo, by hitching a ride with the army that is invading and arriving entirely too late to give any kind of warning.
- With no time to spare, he decides that he and Obi-Wan should sneak on to separate ships and meet up again on the planet surface, presumably hoping these massive ships don't land on opposite ends of the planet.
- As the droids invade Theed, he befriends (but also kind of hates) a native and decides to travel to their home.
- Steals a craft from the leader of said natives and travels to the capital via the planet core. Surfaces in the middle of the river in plain sight, presumably hoping no-one is looking. (Fortunately no-one is looking.)

That seems, to me, like not a strong issue. It's not like he can kill the poison gas.
Considering, they'd been attacked by those droids with forcefields, I don't think it was a bad decision to not continue trying to enter and escape instead.
I think they don't actually know where those are going. Why put themselves in a position where both can get caught in the same place if they do?
I think he used that as a way to cut through the planet core to get the queen.
I think they gave it to him. To me, the plain site thing is a bit harder to avoid as a whole. I think that may be a not smart decision to pop up like that though, I think fair criticism of a choice there. Though I think Obi-Wan was driving.
Qui-Gon fixes Watto's dice. He might as well have strangled him and taken Anakin by force. There's some dubious morals there for a Jedi, but I chalk that up to Lucas not really thinking through his writing or its implications, like much of his writing.
But Qui-Gon is more radical of all the Jedi, he strays from the council and wants to train Anakin because he believes in him. Now he's poorly directed by Lucas which results in a more stoic demeanor, but there's a core to Qui-Gon albeit the messy execution. Neeson helps elevate it by just being Neeson by giving it presence and doing what he can. Interesting idea, bad execution which is pretty much the same destination much of what's in the prequels lead to.
The movie has Yoda outright says that Qui-Gon was defiant, and before that had Obi-Wan say he didn't follow the code and asked him to not defy the council again. Why is it him not thinking it though and bad execution, when I think, to me, the movie seems to reinforce the idea that the character is that?
I like the matter of fact casual-ness of Qui-Gon. I think, if even in a minor way, it differentiates from the cold-ness of the council in The Phantom Menace.
