>>10877164I mean it's alright. I had it for graduate general relativity after having learned and used diffy geo for about a year. Mind you, I was a junior undergrad so perhaps I just wasn't ready to appreciate it at the time.
If you're just starting modern physics, I would recommend just getting something a lot lighter like Carroll's GR book. (That's not to say it's light, but it's not at a research level)
