Grey's Anatomy Season 10 premiered tonight with a highly animated epic two-hour event. After the devastating Season 9 finale, we were on pins and needles waiting to see what would happen next. Did the two-part premiere live up to expectations? Read on for Wetpaint Entertainment's review, and then rate it yourself below!

The episode didn't waste any time jumping right back into the action. The hospital was in shambles, a bunch of firemen needed saving, Richard — and quickly intern Heather after she was electrocuted trying to get to him, thanks to Shane Ross telling her to find him — was on the brink of death, and basically the stakes were super high.

After setting the scene the premiere dove into two of the strongest hours Grey's has had in awhile. We really adored this episode. Let's talk about some of the good stuff.

One of the most interesting pairings of the episode was a guilt stricken Shane working alongside Derek to try to save Heather. We're sad Heather died, but we're really interested to see Shane's arc from here.

Callie and Arizona having to operate on the same person is another good setup. Yes, a little obvious, but we do love it when docs have to deal with strong emotions while also performing to the best of their abilities. Callie walking out on Arizona? Damn. Pain. Tears. We're so upset. This plot is hard to take, but so, so well acted.

And then, of course, there was Richard. We were on the edge of our seats the whole episode waiting to see what happened to him. Having Mer turn out to be the person he'd decided should make his medical decisions was a good twist that makes perfect sense for the characters (even if Meredith was surprised), and was really very meaningful. Sandra Oh and Chandra Wilson also acted the heck out of their scenes. They were both fighting passionately because they both thought they were right and cared so much — great! And really, everything about Bailey in this episode was fantastic.

Other emotional stories: We loved everything with Owen and Cristina; it felt very emotionally honest. The April and Jackson awkwardness made us, as Japril shippers, hopeful, but then April went and chose Matthew, and we are grumpy about it; We were less into Jo and Alex just because it felt a little shoehorned in this week, but we're excited to see more of them in the future.

The biggest drawback to the premiere, in our eyes, was the plot with the firefighters. It was a perfectly solid Grey's medical setup with a lot of perfectly good emotional subplots, but with everything else going on, we had a hard time caring about the guest characters.

Other specific moments we loved: Meredith using her baby to calm Alex down; Bailey tearfully encouraging Cristina through threading Richard's aorta (and her hug afterwards); "I think you should stick with 'I'm sorry you're such a slut'"; Owen and Cristina creating a perfect last time (more than once); the little reminder of George; the interns bonding. Seriously. We're kinda digging the interns right now, finally.

We give it 5 stars. We're glad Season 10 is off to a great start!
