Should i revise and resubmit?

I have just received a decision letter for my submitted paper to an Elsevier journal. It was a revise and resubmit (R&R). Two reviewers comments were included in the decision letter. one of the reviewers suggested minor revisions. The other reviewer on the other hand recommended a rejection and his comments were really unfair. Evidently, he hasn't bothered reading the article completely. I am really disappointed and don't really know how to even respond to his comments. what do you recommend me to do? I am really frustrated.
