This was a wonderful episode. Although I think this could have been better. I can't remember an episode of any TV show where the wedding was the main story where there was no buildup and the wedding so blah. Then again this was April and Andy. The only part I was not a fan of was with Ann and Donna. These are two good actors but this part didn't click with me. I think it's weird that Donna was able to get guys so much more easily then Ann. Granted Ann is coming off two big relationships (Andy, Chris) and Donna has loads of confidence, but it's just weird that Ann can't a guy's number, even a douchey one. I also didn't like Donna's advice to Ann.
Now the wedding itself was something that you may never see. From a outsiders prospective, you may think that NBC and Parks and Recreation missed a chance with the wedding, you don't know Andy and April. Yes, there could've been a bigger buildup, but remember that this was a short season. When April made the speech of why it happened so quickly, that's why there was no buildup. For them (at least for now) it works. I thought the wedding was unique. I loved how Andy had several best men. I also loved how despite her objections, Leslie didn't interrupt the wedding. The dance that Ron had with April was perfect. Also funny in this episode was Orion. It was funny that he was creped out by Chris. I could go on about this wedding but I don't want to take too much of your time.
If you are a true Parks and Rec fan, you would like this episode. If not watch from the pilot and you will be.
