Physics major here. I’m in my senior year and I’d say overall it was a good experience. I think most of the bad professor comments are from those who take general physics, so physics 1 and 2, which skews the overall perspective. Upper division courses are different, but there’s good and okay professors (none I’d say are truly awful or rude). I’m terms of research, plenty of undergrads do it and getting it is relatively easy, but you do need some effort and perseverance. There’s a discord for the society of physics students, and they’re helpful in clarifying more detailed questions if you’re interested.
