I don't think the filibuster should be allowed. It just serves as an end run around the Constitution, which states that bills pass on a 50-50 vote with a tie going to the VP. Having a pre-vote/"Senate Rule" that must get a super-majority before a bill can be voted on is nuts. I supported the nuclear option when my side was in power, and I still support that position. Just because my side isn't in the majority doesn't change things. The gang of 7 had their heads in their butts when they decided the Senate didn't need to follow the Constitution.
