Greatly consistent movie franchises and trilogies

[Jezza]

I've finally been able to see Toy Story 3, since it only came out in the UK today, and I was utterly amazed at how good it was, I'm not saying I was expecting it to be bad because you can't if it's coming from Pixar, but it's not everyday you come across a trilogy or franchise where all the films are as brilliant as each other or start off great and get even better, and this is what promted me to start this thread about which movie trilogies and franchises out there are greatly consistent throughout; because even some of the most highly accalimed franchises in cinema history have one or two down points, such as the original Star Wars and Indiana Jones trilogies; with Star Wars it would be Return of the Jedi and with Indiana Jones it would be The Temple of Doom. So I was just curious to see which movie trilogies and franchises out there where you think all the films are as great as each other, and there isn't a single bad movie in it.

There is one rule to this thread however, and that is this:-

• You can only include a trilogy or franchise if it is complete, because this means you can give a proper judgement on how good it is overall. So don't go including franchises such as Iron Man or the rebooted Batman series, because they've yet to be completed and so you can only make predictions on what the upcoming film is going to be like, not the whole series. I know that in recent years studios have started to do sequels to franchises that apparently ended quite a while ago, but if there is currently no sign of a new sequel coming up, then you can include it.

I understand everyone will have a different view on what they think is great and what is not, but I just thought it'd be a good idea to really see which movie franchises are brilliant throughout, or already start out great and just get better.

So, I'll naturally start off by adding in the Toy Story Trilogy.
