Or which one gets BETTER with each new film.

Mad Max. Evil Dead.

Same with alien

I saw the original Matrix like once and never watched the sequels, so I sat down and watched them all recently. The hate for the sequels is way overblown. Apart from the bad CGI in the second, I thought they were great sequels that took the story in interesting directions.

The Animatrix was a good take on other parts of the universe.

I can respect the fourth one. Sure, it was a terrible movie but it feels like a deliberate piss take on the idea of reviving the franchise. And I can respect that.

I actually thought 4 was better than 2 and 3. Not that 4 was very good, but I thought 2 and 3 suffered from an attempt to, "trilogize," the series and make it a grand epic. It was clear by the end of the third movie that they didn't know where they were going with all of the plot threads they'd set up like Calypso, the Brethren Court, the Jack/Elizabeth/Will love triangle they were hinting at...just way to many ideas and very little payoff. At least 4 told a coherent story in one movie, even if it wasn't a very good story.

5 was one of the most insultingly bad movies I've ever seen.

I thought 3 was a deal better than 2. 2 was generic Hollywood schlock that dragged in the middle; 3 at least attempted some interesting things, and even bordered on artsy at times.

1 was, of course, the best. Haven't seen 4 and 5.

The first movie was a complete package that told a story well, and where it ended was the right place to end it all.

But of course, money.

Really tarnished my feelings about the first movie and I don't think I could even watch it the same way anymore.
