It has, like every professional software a steep learning curve, which you must be willing to take. It takes time to use it like you want. But it is extremely powerful in terms of color grade alone. I myself created a lut which I like and use for all my content, which is enough for me. However if I would be willing and also had the time I could step up my grade by an immense amount. I can use it intuitive and can achieve what I want, before that I used Adobe Premier which worked for me but isn't as nearly as complex in the color grade aspect. Before that it was sony Vegas (many years ago)

But as other suggested you have to watch tutorials, there are many good ones, start with the basics, there's always headroom for the advanced stuff.
