This is a fantastically funny film with real issues. Having brothers i can completely relate, all about un-written rules & sibling rivalry.
Ed Burns really really done well with this, not sure you'd call it a Rom Com but if it is, it certainly is prob the best one i've seen. Now you have to remember this is made on a pretty low budget, not that it show's.
The casting was great in particular the brother who's name i dont know. Aniston who has done a bundle of Rom Com's has not and will not ever beat this cult classic. Diaz also very good, and nasty in this.
But the real Hero of this movie has to be Burns, think i wrote in one of my other review's that he should stick to writing he's own movies as this is also his personnel best.
If you like this check out the Brothers Mcmullen, also a Burns picture, with much of the same cast.
