As for the pilot itself, no comparisons to other shows, it was good but not great. The "fringe" science was completely ludicrous, and I think the show figures that it can get away with foolish science simply because it refers to the science as being "fringe." It felt like they were using fringe as an excuse, and that I didn't like. I also wasn't terribly fond of our crazy scientist, Walter Bishop. Maybe it was the rapidity with which he seemed to return to the normal world, maybe it was his interactions with his son, Peter, but I definitely wanted him to be more normal. Olivia is probably going to get told week after week not to pay any sort of attention to anything Walter has to say because Walter is crazy, and that will not be enjoyable.
While Peter's interactions with his dad weren't great, I did like him talking to Olivia. Their dynamic wasn't new either, but it was at least fun. The way she was playing him at the beginning of the episode was easy to see coming, but at least she copped to it early on, she didn't let him go and think forever that she had the secret scoop on him. From there, the two were interesting. He was put in a hard place, trying to help her and help his dad in order to help her, but it worked.
Finally, Olivia herself. I'm sorry, but I have to say this, she seems like Scully a couple of seasons in – she's seen enough already to know that the truth is out there, but she's not quite ready to accept everything on face value yet. That's a problem. That's just too similar. I assume that as more episodes air this will change, but it just wasn't a great way to start things off.
Where will it all go from last night? Only time will tell.
