I was thinking of giving it 2/4 stars, but the things that annoyed me were:
- the ridiculous tailing in McGarrett's huge, obvious truck; they even drive through a red light and don't miss anyone!
- Quinn and McG spy on bad guys from some building quite close to the baddies; they are not seen and when McG's phone rings, no one hears it
- Tani's totally obnoxious attitude towards the conspiracy geek in the blue-lit room
- utterly stupid conversation between McGarrett and Quinn when the truck's tire is slashed
- little evidence of "show, don't tell"; the various scenes around the "Chat Table" at H50 headquarters consisted of an interminable amount of exposition by people like Adam
Season 10 seems to be not getting off to a very good start; season 9 overall was not that bad, though it kind of petered out at the end...
