WHATEVER YOU DO, DON'T WATCH THE ALTERNATIVE ENDING

Rating: 7/10 (19 September 2019)

I've seen "I Am Legend" about four times now. The Blu-Ray disc that I bought had both the Theatrical version and the Alternative version of the movie on the same disc. I thought I'd look for the differences between the two versions and it all appears to come down to about the final seven minutes of each.
The ending of the theatrical version of this movie was OK and as it should be. A little saccharine but pretty reasonable.
The ending of the alternative version had a "Hollywood ending" with a male Darkseeker showing his affectionate side to the female Darkseeker that Neville has been working on and miraculously cured in his lab. It was just sickening; honestly, I almost hurled.
So, if you buy a DVD or a Blu-Ray of this movie that has the alternative ending, you really should avoid it.
By all means, watch the original theatrical version as it's not at all bad.
