Rabbinic Judaism is basically the surviving sect of the Pharisees who worked tirelessly against Christ and ultimately worked with the Sadducees to crucify Christ. They created the Tradition of men that Jesus constantly corrected. The Holy Tradition of the Jewish people was fulfilled in Christ. His church was built on that Tradition and the fulfilled application of the Law of Moses was understood and properly applied to the church By the Jewish disciples of Christ. I would personally suggest studying Orthodox Christianity instead of the people who killed Jesus out of hate and envy. The Jewish prospective is obviously slanted against losing their place and their people still to this day. Thus they will attempt to show the ancient Jewish culture in a way that hurts your faith in Christ and not help it.
Jesus was a Jewish rabbi with disciples, so he was part of Rabbinic Judaism. Jesus set a sinless example of how to walk in obedience to the Torah, so he was much more zealous for it than the Pharisees were, and he never criticize any of them for obeying it, but he did criticize some of them for not obeying it or for not obeying it correctly. For example, in Matthew 23:23, Jesus said that tithing was something that they ought to be doing while not neglecting weightier matters of the Torah of justice, mercy, and faithfulness, so he was not opposing their obedience to it, but rather he was calling them to a fuller obedience to it in a manner that is in accordance with its weightier matters.
The Pharisees were far from a monolithic group, so what Jesus said about one group of Pharisees should not be mistaken as speaking about all Pharisees. In Deuteronomy 17:8-13, God's word gave authority to priests and judges to make rulings about how to obey the Torah that the people were obligated to follow. In Matthew 23:2-4, Jesus recognized the authority of the Pharisees by saying that they sit on the Seat of Moses and by instructing his followers to do everything that they said, but warned about their hypocrisy. However, there were some Pharisees who also criticized other Pharisees for their hypocrisy, so Jesus was not the only Pharisee to do that. In regard to debate between rabbis Hillel and Shammai, Jesus was virtually in complete agreement with Hillel.
Paul never stopped identifying as a Pharisee (Acts 23:6) and we are told to be imitators of him as he was of Christ (1 Corinthians 11:11), so we are told to be imitators of a Pharisee and most of the NT was written by a Pharisee. Likewise, in Acts 15:5, Pharisees were included among the believers. Jesus and his disciples were all Jews and he spent most of his ministry speaking to other Jews, so there is a lot that we miss or misunderstand if we neglect to study the Jewish cultural and historical context of the Bible. Jesus spent three years with the Pharisees, so they were the people that he wanted to work with, but it was spending a week with the Sadducees that led to his death.
