On the plot side of things, without getting too spoilery, it just doesn't feel like SW in any meaningful way to me. Especially with many decisions regarding the primary factions and their respective places in the galaxy.
On the technical and artistic side of things, I feel like Abrams is focused on objectives other than "make a good Star Wars movie" which isn't all that surprising, considering his reputation for odd (to say the least) artistic and plot choices and a fondness for injecting political subjects into his work.
Most notably, injecting political subjects in a way that doesn't work in-universe. The GFFA has plenty of opportunities to explore such things, but he's not approaching it in that way.
And his biggest response to fan fears that he's going to screw everything up has been "look at how I'm using McQuarrie designs and practical effects! I like SW just like you, right?"
In terms of what Star Wars is, what it means to people, practical vs. computer effects and the use of original concept art is a complete sideshow.
Further, I find the majority of the casting decisions to be iffy, at best, and the new characters have nothing that sells me on them for the most part.
The only ones I find even remotely interesting so far are Poe and Phasma, since Poe is the only one who actually looks worth watching, and I'm a sucker for armor.
Gleeson, for example, is intended to be a general, but looks like a skinny teenager who's hiding in his dad's coat that he found. Kylo? His costume design is... minimalist, to say the least, and that picture of him with his mask off was used as a profile picture on a bait account on an emo dating site for humor value. There's a reason for that.
Will he turn out to be an impressing villain? Maybe, but indications from the lines we've heard so far make it feel like we're going to wish we had Lucas-grade, sand-hating, youngling-killing dialogue back.
Really, I could rant on for another hour or so, but I'll just say that nothing I've seen so far has given me any confidence that they know how to handle what they have.
