Brain dead how? Just what's specifically missing in LR's Tone Curve that you feel makes it a 'toy'?
It works a bit different and less refined than in photoshop.
You cannot use the arrows to move points.
To remove a point it is different as well - in photoshop you just drag the point out in LR it is right click- remove.
I prefer the photoshop curves. It is my nr1 tool.
It is better to have the same tools in both programs.
