I thought the first episode was pretty good. All the voice actors so far have done a great job in getting the characters down. The pacing seems a little fast and itty bitty details are left out, but those are extremely minor.
The only thing that bugged me about it is that it didn't seem as wacky as it should be. I just feel that the funny parts could've been.... funnier and there is the lack of background music which just made the live-action... wacky, haha.

Hmm.... I just have a feeling that I'm kinda biased, so it's probably better to listen to someone who has seen the anime only.
