Many theological writers are saturated with theories rather than with the text. I agree with you there.
The best commentary on the Bible in English is Pilgrim's Progress, once the best seller in English (second only to the Bible), now hardly known or read.
Bunyand, the author, was imprisoned for being a Dissenter preacher. I just bought the Limited Edition of PP, Blake illustrations. for $75. The book is simply astonishing in its handling of the Biblical story.
For those of you with children, get the animated movie of PP. It is a great beginning.
This is the Bible Study tool I use. It has the commentary built in. More commentaries can be added. My son uses it too.
