They might have their faults,but they are one of the most respected,independent broadcasters throughout the world..
I don't think they are as good as they were but that's largely down to the shear hours of news they provide one way or the other now. However good info is buried in it somewhere. Cheaper TV has increase all over and relatively speaking news is one of them. Same with Channel 4 news as well but they can get a bit sillier at times for instance by asking stupid questions. Corbyn and Brexit for instance - a prime example. He has clearly stated his opinion yet still being asked if he is for remaining or leaving. Why do this - it's seen as good telly so loads of sources of all sorts do similar things and in many different ways.
