I have nothing but love for this game. The multiplayer is the best thing I have played since Halo 2. It has a new feel to it and a twist for halo. 343i did a great job. Thanks for refueling my love for halo. (:
I hear you, OP. I’ve only dabbled in the multiplayer so far, as I spent most of my day going through the campaign. But even then, Halo 5 has my third-favorite campaign in the franchise. So yeah, I’m loving this game too. 
I love it as well and, contrast to many reviews I love the campaign a lot too so far.
