Even if you had not seen I.M. 1 this film was enjoyable. Good plot albeit a tad-bit predictable. Scarlett Johansson was a nice addition. Glad to see G. Paltrow had a better/bigger part. Dialogue was well done - fast, witty. Favreau's cameo's were unnecessary and self-serving. Funny that you never see a woman behind the wheel in any car scenes - they are all being driven or saved by someone else (except Johannson's penetration of the Hammer facility). All together an enjoyable "worth paying for" flick.
