Surprisingly a lot of fun!
I wouldn't have predicted me liking 'Mean Girls', but I actually thoroughly enjoyed it. The first half is stronger than what follows and it does wrap up a bit too harmoniously, though all in all it has good intentions and is unexpectedly consistently amusing.
Lindsay Lohan appears in a similar role to what I've seen elsewhere from her across this era, nevertheless she does put in a very good performance. Rachel McAdams is excellent, strangely likeable despite playing an unlikeable character. The rest of the cast are pleasant as well, e.g. Lizzy Caplan, Tina Fey and Tim Meadows.
Interested to see how the sequel and remake turned out. As for this one, it's entertaining!
