What Godzilla films should I buy?

The Sony Blu-rays only come in twos with the exception of Godzilla 2000. But they all include anamorphic widescreen with the original Japanese versions. So they're worth it.

Godzilla vs. King Ghidorah / Godzilla and Mothra: The Battle for Earth
Godzilla vs. MechaGodzilla II / Godzilla vs. SpaceGodzilla
Godzilla vs. Destoroyah / Godzilla x Megaguirus
Godzilla 2000
Godzilla, Mothra, King Ghidorah: Giant Monsters All-Out Attack / Godzilla x MechaGodzilla
Godzilla: Tokyo S.O.S. / Godzilla Final Wars

my list is probably (all of the mosterverse with godzilla 2 when it will be released at disc), gdz vs mothra, vs destoroyah, GMK, 1954 original and that's it... the others are not bad but they are definitely not at the same level

Thanks Jack.D

I already picked a couple up, and don't really want to spend a bunch of money again, but next time I am looking to purchase some Godzilla films, I'll definitely consider these.

This question also begs: What are you looking for in a Godzilla movie? It's sort of hard to recommend films when there's 35 extremely different tones by so many different directors:

I am not really looking for anything in specific. I am going to buy all the movies i can find eventually, I just wanted to start off with what most people think are the best.

You ask 30 Godzilla fans what the best are, you get 30 different answers. 1954 will probably be the one constant.

I for one think the older 50s and 60s films are the best, or generally anything by Honda. Things tend to fall apart by the 1990s.
