If you like the genre and Pacific rim movies/ story then you'll most likely enjoy it. Its not a gem but its entertaining enough. I only wish it was a bit more to the story and perhaps a bit longer.
The plot gives an impression it will be sort of like Firefly or Star Trek, what I mean is the kids have the big mech as their home/travel medium and as they travel around on their "mission" (parents) ,meet people,have experiences,help etc.. All the while the jaeger (big mech) would be their safe comfy home. I would much more prefer it like that, an episodic,every episode a short story while at the same time slowly pushing forward the main storyline.
But as is, the plot is very shallow, the range of their experience is extremely limited with only a handful of characters and even less kaji.
Too bad, because if they put a bit more effort into it and went the other route, with each ep having an individual either action/moral quandry/emotional/sad storyline while staying on the main road, this animation would've been A LOT better.
