is actually the greatest film i have ever seen. go to your pound shop and find it now!
the film starts with a couple being subject to nuclear testing. that's normal. anyway they have a child. also very normal. what isn't is that the child makes his parents spontaneously combust. the special effects are second to none (it looked like they put dummies on fire and shook them and added over the top screaming after).
anyway he grows up and starts burning people, and at the end dissolves into a pool of blue... glow. i don't know.
all in all 10/10 would definitely watch again.
