After seeing Logan it occurred to me that the Wolverine Trilogy is the most bizzare series of films I've ever watched. Never seen three films take such an increase in quality.
1. X-Men Origins: Wolverine - 1/5 Stars
This film can charitably called schlock, but for me everything about it fell flat, the characters, the conflict, the story, and the effects all had sense of being rushed to make a quick buck.
2. The Wolverine - 3/5 stars
Significant improvement over the original and far more repsectable as a film. A solid, but not really spectacular film. It didn't do much that bothered me, but it also didn't blow me away.
3. Logan - 5/5 stars
The important thing about Logan is it feels like a film first, then added mutants to it. Everything about it, the acting, story, and stakes felt raised and the R rating wasn't lazily used. A passion project that showed and of these three the one I know I'll revisit.
So, can you think of another trilogy that consistently improved? From my experience sequels generally get worst as they go along.
