Offshore was my first commercial job with the bare minimum of hours and no IR...but hey, who else will pay for an IR, type you on some of the most popular workhorses around, pay you a good salary, give you more than enough time off a year, and not give you grief for flying when the weather is crap.
Beats any 9-5 job hands down...and I've been there!
As for the work, I love it, gaining invaluable experience from the captains, and landing on a small rig at night on weather minimums is quite a challenge for any pilot (in my opinion anyway).
Yes, some people will find it monotonous, and there are more glamorous and exciting jobs out there I'm sure, and maybe one day I will try something different but, for now, I love helicopters and I love my job, go for it.
