Above is a link to information about the MFS fund in Morningstar, the largest database of mutual fund information. Overall, it's quite expensive. You pay 1.72% per year just to own this fund. It's a sector fund, concentrated in stocks of the utilities sector.
I can't tell you whether your advisor is good or not. I use Vanguard for my mutual funds. The weighted average expense ratio for my portfolio is about 1/3 of 1%. Vanguard has the lowest expenses and some of the highest rated funds in the industry. But here's the thing: you do everything online. You can talk to an advisor, but it's on the phone. That's why costs are so low. If you need an advisor you can meet with face to face, you will pay (in most cases a lot) for that privilege.
