I think it's an excellent pilot episode. I'm usually not a fan of pilots for the same reasons that you've stated already, but you can tell that a lot of work went into creating the characters and their backstories before filming. The characters are all there, fully formed and wonderful.

The only moment in the pilot that really annoys me is when Toby manages to wipe the vital data off the drive by putting it too close to the magnet in the speaker. He's a genius, he should have known that would happen! And even if he momentarily forgot, Happy should have known! Apart from that, it's a brilliant episode and I re-watch it regularly.
