Another reviewer did write that as his summary and I would agree with that. You don't have to love Melissa (not only main role, but also script writing duties apparently as IMDb states),but if you hate her, this movie is not for you. It's a character that has a basic concept she has played in other movies too. So you'll know if you like that or not. But you get an added Susan Sarandon to that (amongst other really good actors).

Putting this group together was genius and everyone is pulling their weight. You still have to be able to like the humor/jokes they are spitting, otherwise you'll be left empty. The movie is predictable even if at first it seems not to have a goal it wants to reach. It still has quite some passages that could be better and not everything is completely convincing. But the movie itself is a nice watch overall

.... take a road trip and get a lesson in love & hate!

This flick isn't as bad as so many reviews are claiming!! It's another in a long list of 'life lessons learned while on the road movies' with plenty of (not guffaw moments) but plenty of light hearted laffs and chuckles.

Melissa McCarthy knows she has created this bloated sassy bitch with a kind and well meaning heart character, and she is taking it to the box office to cash in because plenty of people think she's funny. In 'Tammy' she has plenty of Hollywood names around her .. Susan Sarandon and Kathy Bates being most prominent and doing their role well.

As a simple comedy it works fine. I don't think for one moment there is some meaningful message so many viewer seems to be seeking. It's just Tammy & granny hitting the road because they are tired of their daily routine and seek something different .... in Niagara Falls ... and they find their goal. And tear-up plenty of stuff on the way!

It's a good movie!

You know, if this movie had a tone and stuck to it, this might have been an enjoyable flick to watch. But first, it tries to be slapstick-like at the beginning, then more light-hearted in giving the characters a good time, and then a little dramatic concerning the near-death of one of those characters. The result: Tammy is mostly boring even at a little over 90 minutes. I liked Melissa McCarthy (who co-wrote this) and Susan Sarandon as her grandma singing The Allman Brothers' "Midnight Rider". And some of their dialogue exchanges had some charm. But mostly, I was just underwhelmed by the whole thing. Oh, and Dan Aykroyd as McCarthy's father was a not-too-inspired cameo. So on that note, I can't recommend Tammy.
