Pros
If you're the type of person who works hard during the day, and is self-motivated to see the company you work for succeed, you'll do great here. There are quite a few people who have been there for a few years, and three people who were there, left, and came back. That's always a great sign and to me, was awesome to hear when I was unsure after reading some of these reviews.
Cons
If you don't have the ability to run with things, be independent, proactive, responsive, this likely isn't the place for you. In large agencies it's easy for those who don't perform exceedingly well (let's say, a 7 out of 10 employee) to be camouflaged a bit more. Since this is one open concept studio, those 7's can look like 5's pretty quick. It's also a dictatorship – it's owner operated, so that's pretty much par for the course at any company like this. If you know that going in, you'll be fine. It can catch people off guard.
