If that's what you are looking for go there. I didn't go to Rams games in the coliseum as a kid and am underwhelmed by it now. Haven't seen the new improvements, but keep these points in mind:
There's no concourse - so if you want food or beer you have to walk outside the stadium
In Sept Oct day games you will be blasted into submission by the sun
Parking is a nightmare and mass transit away from the game is just as bad, if not worse.
There's no where to tailgate except for one or 2 permitted lots.
You do, get the history of the building which is cool, except for the peeling paint, crumbing concert, ancient bathrooms and narrow tunnels to walk through (was everyone smaller in the 1920's?) Some of these may have been corrected with the update.
There are usually a lot of opposing team fans at the game too, so they don't feel 100% like a home game that you get, in say - Denver.
