It took me a bit to accept and adapt to the changes, but, in my opinion, it's worth it. I mean, Aunt May is hot, Mary Jane is a skinny black girl and Ned Leeds is not only NOT the Hobgoblin, but he's Peter's best friend. All massive deviations away from the source material. Yet, billions of dollars don't lie.
I'd say give the first episode a chance, turn off that inner voice we all have that tells you this isn't the way is has to be and see if it doesn't grab you. It may, it may not. I do think it deserves a chance if you enjoyed the books.
