Teddy, who has left college but is struggling to move on from his partying days, helps the girls set up their renegade sorority.
It's not long before Shelby cuts "old" Teddy loose and he finds himself playing for Team Mac and Kelly as they try to evict the girls.
Though it's refreshing to see college life to be portrayed how it really is, and for Mac and Kelly to be shown as well-meaning but terrible parents, the comedy quickly reverts to the gross and stupid, and relies on familiar gags.
More swearing, sex toys and bongs don't add a lot, although the repeated appearance of a car airbag gag belatedly delivers genuine laughs.
If you enjoyed version one, you'll find something to chuckle over this time as well, and it's good to see female characters treated with a little more respect.
If nothing else, it's fun listening to Rose Byrne swear in an Aussie accent.
Verdict: Same as before but with a feminist bent.
