I have used the process outlined here https://www.iamthejeff.com/post/32/the-best-way-to-color-correct-c-41-negative-film-scans and find it very good. So getting a good result in Photoshop is quite easy. I have used this procedure in Photoshop to create a LUT and then a Camera Raw profile for a few different negative colour film types. The results in Lightroom are reasonable, but with Lr develop adjustments working on the negative, the tone adjustments are reversed and many others cannot be used because they produce wild colour shifts, such as vibrance and saturation. The white balance and auto tone tools are useless too. A bit of manual adjustment of WB works. Here is an example of a DSLR 'scanned' film negative with one of my profiles applied.
And after a bit of adjusting
It would be so much better to have a tool or tool set that could do these steps natively in Lr so that all the develop tools can be used normally on a raw image.
A negative tool has been asked for by users for 7 years now and it is so disappointing that Adobe hasn't even given those users the courtesy of responded to the requests. Not even to say 'No we will not be implementing a negative function'. Just nothing, completely ignored. Like myself, there are many photographers with considerable archives of film negatives who are experimenting with DSLR 'scanning' to digital raw and would dearly love to process them in Lr. It's hardly rocket science, with a good starting point being an invert option coupled with a remove film mask colour cast (not by changing white balance) so that all the Lr develop tools work as normal.
